Yeah, that's pretty close. I was actually thinking his guy would have an OPS somewhere between my two guys. .690ish. Pretty damn close to your guy.
Using my formula, it's closer than I thought it would be. P2 by about 5%. Eyeballing it, I thought closer to 10%.
That would be a nice little tweak but, once the WC bracket pops up, it's easy enough to figure out at a glance.
