I've tried to remove gaps
The I've ran the game by SH3cdr. Result :
1- The crews lost resistance very slowly; it's right for this model.
1- The crews recover, it's not right for this model.
2- The basic.cfg in SH3 has returned to original values for the paragraph [CREW-X], but the paragraph [FATIGUE_COEF] has changed with Kaa's values.
When I run the game with SH3cdr, the CREW_X values don't changed by the fatigue model selected in SH3cdr settings. Only the FATIGUE_COEF values are changed

Strange, no ?
I've desinstall/reinstall the game and it's always the same problem
My install
1- SH3
2- Patch 1.4b
3- SH3 commander + new crew fatigue models.cfg
4- JSGME
5- IUB1.01
6- optional mods heavy harbor
