Items, ships, planes and land units all contribute to the power
factor, which determines position on the power chart.
Items are worth
amount * item value * (0.5 + nation tech level / 1000.0)
The item values aren't quite right: producing stuff can *hurt* your
position on the power chart. Food, uw and rads are worth nothng.
Reduce the value of oil, and give rads the same value as oil. Tweak
value of iron and oil products so that production's power change is
roughly zero around p.e. 0.9 (tech 110), except for construction
materials, where it's zero at p.e. 0.5 (tech 0). Construction
materials become less valuable, shells, guns and petrol become more
valuable. Increase value of bars to roughly match the other changes.
It may still be too low. Halve the value of civilians, and give the
other half to uw. Results:
old new change
civ 100 50 / 2
mil 100 100
shell 80 125 * 1.5625
gun 400 950 * 2.375
pet 2 7 * 3.5
iron 10 10
dust 200 200
bar 1000 2500 * 2.5
food 0 0
oil 100 50 / 2
lcm 100 20 / 5
hcm 200 40 / 5
uw 0 50 new
rad 0 50 new
Ships, planes and land units are worth
base value * effic/100.0 * (0.5 + unit tech level / 1000.0)
For ships and land units, the base value is
lcm/5.0 + hcm/5.0
Build cost is ignored, but lcms are valued twice as much "loose" ones
(before this commit). Therefore, building stuff can change your
position on the power chart in both directions, depending on the type
of build.
For planes, the base value is
20 * (0.5 + nation tech level / 1000.0)
Build cost and materials are ignored, and tech is squared. This
is plainly absurd.
Unify to
(power value of money and materials to build) * effic/100.0
This formula is chosen so that building stuff doesn't change your
power factor. Bonus: it doesn't assume anything about possible build
materials.
For ships and land units, factoring in build cost overcompensates the
discounted value of construction materials more often than not.
Noteworthy changes for the stock game:
ship type old new change
ss slave ship 20 5.8 * 0.29 largest decrease
cs cargo ship 20 7.8 * 0.39
ts trade ship 60 25.5 * 0.42
frg frigate 12 7.8 * 0.65
bb battleship 24 21.8 * 0.91
cal light carrier 22 30.4 * 1.38
can nuc carrier 30 84.6 * 2.82 largest increase
land unit type old new change
hat hvy artillery 12 9.6 * 0.8 largest decrease
linf light infantry 2.4 3.32 * 1.38
cav cavalry 3 5.4 * 1.8
inf infantry 3 5.4 * 1.8

com commando 3 15.4 * 5.13
eng engineer 3 30.4 * 10.13
meng mech engineer 3 45.4 * 15.13 largest increase
For planes, the power value change depends on the type. Below a
certain nation tech level, planes of this type become more valuable,
above less.
For the stock game, planes costing at most $1000 become less valuable
at any nation tech level that can build them, and planes costing at
least $1800 become more valuable at any practical tech level,
i.e. under 400. Noteworthy planes:
plane type new
sam Sea Sparrow 2.1 least valuable
f2 P-51 Mustang 4.34
lb TBD-1 Devastator 5.92
jf1 F-4 Phantom 10.6
tr C-56 Lodestar 10.78
jt C-141 Starlifter 15.86
jhb B-52 Strato-Fortress 33.54
ss KH-7 spysat 41.2 most valuable
The old value is a flat 12 at nation tech level 100, 15 at tech level
250, and 18 at tech level 400.

.NA power "Display arbitrarily measured strengths of countries"

.LV Basic

.SY "power [new|update] [<NUM>|country <NATS>]"
|
|
The power report provides one view of national strengths.
|
|
It can be particularly helpful in planning defense strategies.
|
|
.s1
|
|
Normally, the last saved power report is shown.
|
|
The optional arguments \*Qnew\*U and \*Qupdate\*U request a new power
|
|
report based on up-to-date information.
|
|
This costs 10 BTUs.
|
|
The new report is saved for use by future power commands, except when
|
|
a deity uses \*Qupdate\*U. This lets deities examine up-to-date power
|
|
reports without affecting what players get to see.
|
|
.s1
|
|
If option AUTO_POWER is enabled, the command doesn't let you save new
|
|
power reports. Instead, the power report is updated automatically
|
|
right before the update.
|
|
.s1
|
|
If the optional \*QNUM\*U argument is given, only the
|
|
top NUM entries in the power chart will be displayed. Note that for
|
|
deities, if you give a negative number, only the top NUM entries in
|
|
the power chart will be displayed, and the power number rating will
|
|
not be displayed.
|
|
.s1
|
|
If the optional \*Qcountry\*U argument is given, then the information
|
|
is given for those particular countries.
|
|
.s1
|
|
In the power report the countries are listed
|
|
in order of decreasing \*Qpower factor\*U.
|
|
Powerless countries are not shown unless explicitly requested with the
|
|
\*Qcountry\*U argument.
|

The power report shows the following columns:

The \*Qpower factor\*U is determined by the following equation:
|
|
.s1
|
|
.NF
|
|
power factor = ( power value of money
|
|
+ power value of sectors
|
|
+ power value of commodities in sectors
|
|
+ power value of commodities loaded on ships and land units)
|
|
* (20 + nation tech level) / 500
|
|
+ power value of ships, planes and land units
|
|
* (20 + their tech level) / 500

The power value of a sector is efficiency / 10.

The power value of a ship, plane or land unit is the power value of
