Again, my sheet has nothing to do with munk's tool. This sheet was created using the formulas found on the Utopia Wiki, and I just went through and verified that my spreadsheet matches the formulas found in the wiki. I cannot speak for the discrepancy between my tool and munk's, only that if you're trying to point out errors within mine that you should refer back to the UtoWiki or link me a thread containing the correct info.
With that said, I did notice that on my spreadsheet the offense and defense values (not OPA/DPA) are off by 2.8pts and 1pt respectively. This is well within my margin of error, however, so I'm going to leave it as is. I should note that these calculations I used only 1gen as that's a more realistic scenario and gives a more accurate look at what needs to be corrected.
EDIT: Updated the OP of this thread with a link to the most recent version; not sure why I didn't think to do that sooner.
