Tom, sorry to continue to beat on this, but I'm still wondering. I've just plugged the raw numbers for Verlander, Kershaw, Weaver, and Hamels into Excel, and this is what I'm coming up with:
Verlander = 1.92
Kershaw = 1.997
Weaver = 2.27
Hamels = 2.23
These are very very close to the values reported on baseball-reference (all within 0.01). But quite different from the results listed here. Is it remotely possible that either (a) the formula has a parenthesis misplaced or something causing it to compute slightly differently or (b) perhaps one of the input values is off?
