In Commander/Cfg/crew fatigue model you can adjust values to your liking.
Ie stock SH3, modify all lines COEF|
Increase value increase fatigue (or endurance) rate... until you find the graal

There are 12 different compartments (including Flak/Deck gun station)
You can have different fatigue rate per compartments. Hardest thing is to figure the lines corresponding to compartments!
So in the Diesels room, it could be more tiring than in Command room etc
And...there is also the bad weather factor, wich can increase the fatigue too (important for deck station)
Onealex fatigue model is quite nice in that matter. That’s even the first time i enjoy playing with crew fatigue on....
