That's assuming OOTP produces a realistic number of groundouts, but I'd assume it does, considering how well it models most stats. Still, the difference probably isn't worth worrying about.
It was fun, and do post an update about the results of your spreadsheet work. I imagine it might be very useful when making roster sets from real life players.

From what I've seen, the % of groundballs reflects the % in the GB rating for each pitcher. It's incredibly close over the course of a seasons.
So as long as the game models GB rating realistically, the % of groundballs should be realistic.
That said, I think I'll just use your basic HA formula, just to avoid the extra work of adding the GB part.
I'll try to post my results in the other thread when I get a minute. I wish I could post a spreadsheet, but I don't know how, and I don't know if it's safe to do so.
I just took the numbers we came up with and plugged them into Bill James's (very) basic Runs Created formula. Off the top of my head, I think it is ((H + BB) * TB) / (H + BB).
Now I know that RC formula doesn't account for GIDP, SB, CS, HP, SF, SH, etc.... But James's says it's 90% accurate, and that's close enough for me. I have been building teams in the Billy Beane manner (i.e. few basestealers, lots of walks & HR). So SB isn't that important to me. I don't use SH or SB much. And I figure GIDP evens out over time (except for really slow guys.)
So that basic RC formula is what I plugged into excel after I found the calculations for H, BB, and TB.
You showed me that Contact was related to Hits. I then took H - doubles - triples - HR to get singles. From there, total bases was a cinch.
