Q. When a player fatigues below 100, is the number a pct of his ratings(95 is 95 % of his ratings ability).
A. No, it's not linear.
From that, I'm reading the implication that fatigue affect his ratings ability, but not linearly (ie. therefore, on a curve)
And really, when you think of it, what 0% pitcher in the minors shoots the lights out?
