What I'm saying is that the upper end of the fatigue scale for a typical starting pitcher might be somewhere like 130-140 or so, but is only displayed as a max of 100. What the actual number is appears to be dependent upon his durability/stamina combo. I've never bothered to try to figure out the formula.
But in your example, assuming that every pitch accounts for around 1% fatigue, if he starts the game at 132% (showing as 100%), his 85 pitches will bring him down to 47% after the game, where if he started only at 120% (again, showing as 100%), his 85 pitches will bring him down to 35% after the game.
That's why I've been saying all along that, with respect to fatigue, all 100%'s are not the same.
