I'm positive that in a pitchers park, the difference between an 85 and 50 PC with an above average arm all in is about half a run in ERA, which is 81 runs a season.
Their is no way that can be correct. 81 runs is a HUGE. In a neutral park a 80 across the board hitter only creates 100 to 110 runs a season in 625 PAs.
If only there was a way to check such a thing.
Oh, wait, there is. Stats last forever. Check them.
Then come back and say "Small sample size".
But I'll tell you right now that there is a pattern. And it really is noticable to those who check.
