FH2 Hi said something that may be good even in realism.
I don't know how in the mod, the stamina will be executed. but have you ever tried to run with an army packaging?, man we need Hulk endurance for the common people. And as we know, the soldier that were shipped to war, were not always ''trained'' as it should. so here is what I suggest.
Only for the speed function.
it gives a little amount of time to run, when i say little, I means about 5 second. SO if we have a ''adrenaline bar or stamina bar'' and we just pass it out, maybe a little extra of 5 second could be use. It could be the same for the jumping, I don't remember in which game this was happening.
Each jump drain a lot of stamina, (with 90lbs of stock, it's almost impossible to jump to often).
I don't know if you can understand what I mean...
