Underwater range and endurance

One interesting item, the CFG file;

[Unit]
ClassName=SSSargo
3DModelFileName=data/Submarine/NSS_Sargo/NSS_Sargo
HumanPlayable=YES
Interior=data/Interior/NSS_Salmon/NSS_Salmon
UnitType=200
MaxSpeed=2
MaxSpeedSubmerged=1
Length=94.6404
Width=8.1788
RenownAwarded=130

The percentages at the bottom;

[EngineProperties]
AllStop=0.00
AheadSlow=0.20
AheadOneThird=0.40
AheadStandard=0.62
AheadFull=0.85
AheadFlank=1.00
BackSlow=-0.26
BackStandard=-0.40
BackFull=-0.53
BackEmergency=-0.66

Are applied to both surfaced and submerged speeds, but the max speeds at the top are not used in game - those come only from the SIM file, change the speeds in the CFG to whatever and it has no effect.

In the sim file I have;

Propulsion
Max speed = 25
Max force = 0.0
eng power = 6140
eng rpm = 280

E propulsion
Max speed = 12
eng power = 2660
eng rpm = 270

Power and RPM are default, the only thing I changed was the max speed.

For the submerged range I just now tried;

miles = 4
knots = 15

3 1/2 hour recharge from 10%

2 knots
68 miles

5 knots
34 miles

7 knots
20 miles

10 knots
34 miles

12 knots
30 miles

Really odd that whatever you do has more effect on the recharge time than anything else, and why the range for 5 knots and 10 knots are the same is completely baffling.

Only drag I can find is up/down and left/right, no idea what that applies to - induced drag fore and aft will increase with speed and would not drop off except with a planing hull (or hydrofoil), which certainly doesn't apply to a WWII submarine - especially when submerged. But the increase in range from Standard to Full speed seems to be more or less consistent.
