Ship, plane and land unit repair uses new work, except in sectors
owned by countries with a higher country number.
This inconsistency is an artifact of how the update is sequenced: we
work on countries one after the other. A country's ships, planes and
land units get repaired before higher-numbered countries' sectors
produce. Any ship, plane and land unit repairs in such sectors use
old work instead of new work.
Repair work use changed several times during Empire's history.
In BSD Empire, repairs use old work, because it updates ships and
planes before sectors.
Chainsaw added budget priorities and the budget command as option
BUDGET. Budget priorities let players choose separately for ships,
planes and land units whether to use old or new work for repairs.
The option also changed the update to work on countries one after the
other, presumably to permit a more efficient implementation of the
budget command.
Chainsaw also introduced repairs in foreign sectors under option
ALLYHARBORWORK.
With BUDGET disabled, all repairs still use old work, whether at home
or abroad. With BUDGET enabled, work use of repairs at home depends
on budget priorities, but work use abroad depend on country numbers.
Both options became standard in Empire 2.
Since v4.3.6, repairs at home always use new work (commit 967299a and
commit 520446e).
To make repairs abroad always use new work as well, we need to update
all sectors before any ship repair. This is straightforward: split
the loop over countries between sectors and unit building. For
symmetry, also split it between unit maintenance and sectors.
The budget command is differently broken, and will be fixed next.

Land unit maintenance and building ignore land units in sanctuary
sectors. Leftovers from undocumented compile-time option START_UNITS,
which is gone since commit dab1f0b, v4.3.0. Feeding, paying military
and fallout don't ignore them. Change maintenance and building to
match.
Sector preparation (except for the fallout part) and production ignore
even non-sanctuary sectors owned by nations in sanctuary. Fallout,
delivery, distribution and mobility growth don't check the sector
owner's status. Change preparation and production to ignore just
sanctuary sectors, without checking the sector owner's status. Except
don't bother for most of fallout, as we already avoid spreading
fallout into sanctuaries; still ignore sanctuaries when doing fallout
damage mostly for completeness.

When option TECH_POP is enabled, the cost of tech increases when
civilian population exceeds 50000. Only civilians in old-owned
sectors count. This differs from education and happiness, where
civilians loaded on ships and land units count, too.
The update counts population for TECH_POP with count_pop(). This is
an extra pass over all sectors.
produce also uses count_pop(), once per tech center examined.
Wasteful.
budget avoids count_pop(): it uses tax()'s civilian count. More
efficient, but the difference to the update is ugly.
Change TECH_POP to use the same civilian count as education and
happiness, i.e. count civilians on ships and land units, too.
This count is available in nat_budget[] in time for produce(): it's
computed by tax() and by ship and land unit maintenance. So use it
there. This takes care of the update and budget. produce doesn't run
enough update code to do the same. Keep calling count_pop() there.

Per-civilian happiness and education production is raw production
divided by the number of old-owned civilians. The update reports the
number of old-owned civilians ("total pop was %d").
This number of civilians is also used by budget to predict cost of
tech when option TECH_POP is enabled, but that doesn't match how the
update computes the cost. To be fixed next.
Civilians loaded on ships are only counted by the update, not by
budget. Harmless, as budget doesn't compute happiness and education.
Civilians loaded on land units are ignored by both. None of the stock
game's land units can load civilians.
Civilians in sectors are counted before plague deaths, and in ships
afterwards.

Sector production computes a number of intermediate values, and rounds
many of them. We've tinkered with the rounding a few times. It
currently works as follows.
There are two production efficiencies, both shown by the production
command: sector p.e. (column eff) governs how efficiently work is
converted to units of production, and p.e. (column p.e.) governs how
much product each unit of production yields.
Production is limited by available work, materials and resource
contents. These limits are all rounded down.
Example: if a unit takes 16 work (tech or guns), then 600 work at 100%
sector p.e. can make at most 37 units, rounded down from 600 * 100% /
16 = 37.5. 76 work at 76% sector p.e. can make 3, rounded down from
76 * 76% / 16 = 3.61.
Output is units times p.e. Level output isn't rounded. Item output
is rounded down.
Example: a tech center making 37 units at p.e. 0.6 (edu=20) yields 37
* 0.6 = 22.2 tech (before tech log). 3 units yield 1.8 tech.
Example: a defense plant making 37 units at p.e. 0.6 (tech 35) yields
22 guns (rounded down from 22.2). 3 units yield 1.8g, randomly
rounded.
If item output needs to be adjusted downward (production backlog), the
number of units made is likewise adjusted. It is rounded randomly.
Example: a 100% refinery with 156 work can make 156 units. Its
p.e. at tech 30 is 5.0, so this yields 780p. But if it already has
9500p, it can make only 499 more. That's 99.8 units, rounded randomly
to either 99 or 100.
Materials and money consumed are a multiple of units made. No
rounding there.
Resource depletion depends on units made and is rounded randomly.
Work consumed is units made times work per unit divided by sector
production efficiency. Rounded randomly. Any work left can normally
be used at the next update (it "rolls over").
Example: the tech center making 37 units consumes 37 * 16 / 100% = 592
work, with 8 work left. It also consumes 37d 185o 370l $11100.
Example: the tech center making 3 units consumes 3 * 16 / 76% = 63.2
work, randomly rounded to 63 or 64, with 13 or 12 work left. It also
consumes 3d 15o 30l $900.
Example: the defense plant making 3 units consumes work the same. It
additionally consumes 1o 15l 30h $30 when it makes one gun, and twice
as much when it makes two.
Rounding intermediate values like "units of production" is awkward.
It's better to round only final results. These are item output,
materials consumed, resource depletion and work consumed. Round item
output down, and the rest randomly. Don't round level output (it's a
floating-point value) and money consumed (also floating-point, since
the previous commit).
For item production, this shifts the random variations from number of
products made to materials and work consumed.
Example: the first defense plant again makes 22 guns (now rounded down
from 22.5). The second one now always makes two guns (rounded down
from 3.61 * 0.6 = 2.166) instead of 1.8 randomly rounded.
This is nice, because budget and production can now predict the number
of items made exactly. Before, budget fluctuated randomly just like
the update, and production rounded down.
Note that budget used to be even worse: until commit 6f7c93c
(v4.3.31), we rounded units of production randomly rather than down.
The 100% tech center randomly made 37 or 38 units, which is much more
relevant than random rounding of item output.
Furthermore, work is now fully used both for item and level
production, to the limit permitted by materials and resource contents.
Example: the first tech center now makes 37.5 units, yielding 37.5 *
0.6 = 22.5 tech. It consumes 37.5d 187.5o 375l $11250 and all 600
work (fractions randomly rounded).
Example: the second tech center now makes 3.61 units yielding 1.805
tech, consuming 3.61d 18.05o 36.1l $1083 and all 76 work.
The production command duplicates much of the update's sector
production code, so it needs a matching update. The next commit will
reduce the duplication.

The update tallies income and expenses in full dollars. Each debit or
credit is rounded before it is added to the tally. Different things
are rounded differently. Examples:
* Each sector's military pay is rounded down. In the stock game, 1m
is paid $4.999998, so n mil cost n*$5 -$1, for all practical n. 10m
in one sector cost $49, but spread over ten sectors they cost only
$40.
* Total pay for military in ships and land units is rounded down.
* Each plane's military pay is rounded down (used to be rounded up
except for broke countries until recent commit 2eb08f4). In the
stock game, flight pay is 5 * $4.999998 = $24.99999. For a plane
with n mil, that's n * $25 - $1. Filed under plane maintenance, not
military payroll.
* Each sector's civilian tax is rounded. In the stock game, 1c pays
$0.499998. 10c in one sector pay $5, but spread over ten sectors
they pay nothing.
* An occupied sector's civilian tax is first rounded, then divided by
four and rounded down *boggle*.
* Each sector's uw tax is rounded. In the stock game, 1u pays
$0.106662. 1-4u in one sector pay nothing. 5-14u pay $1.
This is madness. Has always been that way.
Drop the rounding and track money in type double throughout the
update. Round only the final amount, randomly. This is similar to
how commands accumulate a money delta in player->dolcost.

When we add up military payroll, we discard fractions. Payroll is
therefore lower than it should be, but I'm not fixing that now. The
number of military budget reports is actually computed from payroll,
and therefore also low.
The obvious way to fix that would be adding another out parameter to
tax() and upd_slmilcosts(). However, budget and the update track cost
and count of numerous things (sector products, unit maintenance and
building, ...), and it's time for a common way to do that.
Create struct budget_item for tracking cost and count, and struct
budget nat_budget[MAXNOC] for tracking a nation's budget. Track only
military for now; more to follow.
This fixes the military count. The cost of military remains low,

Traditionally, unused unused available work is discarded at the
update. Since commit d7a054c (v4.2.13), deities can configure (some)
unused work to "roll over", i.e. available work = some unused work +
this update's work.
Not discarding unused work reduces micromanagement incentives.
However, it also leads to unobvious behavior.
For instance, here's the obvious way to build a radar station: move in
enough people to make 200 work. Half of it is available for sector
building, and increases efficiency to 100%. Here's a not-so-obvious
way: move in enough people to make 134 work. 67 will be used to
increase efficiency to 67%. Now move your workers elsewhere. The
unused available work is enough to finish the job at the next update.
Similarly, neighbors could be surprised by sectors building bridges
despite having no visible workers.
Commit 7f4e59f (v4.2.15) let deities limit the amount rolled over:
unused work above rollover_avail_max is discarded. This became the
default with a value of 50 in commit 81a3e4c4, v4.3.31.
Limit it further so that "roll over" can increase the update's work by
no more than half, plus one. The extra point is there so that even a
tiny work force has a chance to eventually eke out the second point of
work needed to increase efficiency.

Rounding work down can lead to a bit of work micromanagement. For
instance, four military on a lonely island accomplish nothing in 60
ETU updates, but five will make one point of work per update. They
can build a 2% harbor in four updates, as long as rollover_avail_max
is at least 3. Six to eight will be no faster.
The people's work used to be rounded randomly until Empire 3's big
effort to make the update code work for budget switched to rounding it
down, perhaps accidentally.
Switch back to rounding randomly, so that players don't have to get it
exactly right. Four military now get to 2% in five updates on
average, five in four, six or seven in three, and so forth.

The collection value of a sector is
sector value = sector type value * (sector efficiency + 100)
+ sum of item values
item value = item type value * amount
The sector and item type values are configurable.
The item type collect values aren't too far off the power values:

1 "m" 100 0 inf
2 "s" 125 5 25

11 "h" 40 4 10
12 "u" 50 1 50
13 "r" 50 150 0.33
The power value is very roughly ten times the collect value, except
for civilians and uw it's 50, for rads its 0.33, and military are free
to collect. The latter two make no sense.
Replace the item type collect value by the power value / 50 for
people, and by the power value / 10 for everything else. This makes
collecting military, shells, guns and uw more expensive, and petrol,
bars, iron, oil and rads cheaper.
The sector type values are basically arbitrary. For instance, an iron
mine costs five times as much as a wilderness, but a third of an
uranium mine, regardless of actual resource contents.
Replace this by different arbitrary values:
sector value = (item value of materials necessary to build it
+ build cost) * efficiency / 100
+ sector type maximum population
+ sum of item values
Some sector types become cheaper, some more expensive.

shiprepair() limits the efficiency gain to how much the workers can
build, rounding randomly. It charges work, money and materials for
the efficiency actually gained, rounding work up, money down, and
materials randomly. Same for planerepair() and landrepair(). Has
always been that way.
If you get lucky with the random rounding, you may get a bit of extra
work done for free.
The budget command runs the update code, and can be off by one due to
different random rounding.
Sector production used to have the same issue, only more serious,
because a single unit of tech production matters much more for the
budget than a single point of unit efficiency gain. I fixed it in
commit 6f7c93c, v4.3.31.
Fix it for unit building the same way: limit efficiency gain to the
amount the workers can produce (no rounding). Work becomes a hard
limit, not subject to random fluctuations. Randomly round work and
money charged for actual gain, like we do for materials. On average,
this charges exactly the work and money that's used.
This lets budget predict how much gets built a bit more accurately.
It's still not exact, as the amount of work available for building
remains slightly random, and the build cost is randomly rounded.
The old rounding of work for ships carries the comment "I didn't use
roundavg here, because I want to penalize the player with a large
number of ships." Likewise for planes. Rounding work up rather than
randomly increases the work cost by 0.5 per ship, plane or land unit
on average. I could keep the penalty by adding 0.5 before random
rounding. Not worth it, since the effect is actually pretty trivial.
Let's examine a fairly extreme case: an airfield with 600 available
work repairing a huge number of lightly damaged planes, say f2 with
81% average efficiency. The old code lets the airfield repair roughly
600 / 6.5 = ~92 planes, the new code 600 / 6 = 100.

The value of ordinary sectors (maximum population 1000) doesn't
change. The stock game's mountains, plains and bridges are now worth

This concludes my tweaking of the power factor for now. I tested it

overtakes #4, and the lead of #1 over #2 and #3 shrinks some. Closer
analysis finds the following reasons. The game had very expensive big
cities. Valuing them correctly gives countries with many cities a
noticeable boost. Planes are worth less than before, but the
difference is much larger for cheap planes. Big piles of construction
materials are worth much less, and shells, guns and bars are worth
more.

Building sectors can make you rate *lower* on the power chart, because
the power factor treats all sectors the same, regardless of build
materials and cost.
To avoid that, replace the term
efficiency / 10.0
by
(power value of materials + power value of cost + 9)
* efficiency/100.0
The value of ordinary sectors, which take no materials and cost $100,

to its materials and higher cost. The stock game's wilderness is
worth 10% less, because it costs nothing.
