@DCEBB - I think my wording may have been imprecise. I understand that the OVR value is derivative from the other ratings, and that FBGratings rates the players based solely on their scouted skills and the OVR rating calculation is left to fall wherever it may. To the extent of football gameplay I don't really care about the OVR rating.
The reason I remain concerned with the OVR rating is because it's my strong impression that that rating along with player age is what drives the CPU roster management logic within Connected Franchise. The true mean ratings from your site from back in May (the ones I play tested for a good bit) resulted in higher in-game OVR ratings across the board with which to drive that logic compared to the equal interval set on your site now (which remains more true to your primary source data, I would assume), so my guess is that it'd be more likely to cooperate for the first few years of CFM at least before rookies disrupt the player pool but so much. In Madden 25, at least, it's my strong impression that rookies aren't rated the same way Donny Moore rates players just from eyeball observation, so it may cooperate better than expected.
To the extent that your site now provides only the equal interval ratings as that more truly maps with the scouting data you are provided, I was simply planning on
transforming the mean and standard deviation for certain "intangible" ratings per-position (i.e. not SPD / STR / AGI / ACC) from what currently exists to that of Madden 15's default roster set. That doesn't appear to match how you generated the true mean ratings in the first place based on what you describe. However, absent the knowledge of how you create the true mean ratings, it was the best thing I could think of to do to raise the OVR rating to something the GM AI would cooperate while keeping individual player ratings true to your original source data (relatively speaking).
I'm plenty open to discussion on this, maybe you can tell me if my line of thinking for my set of concerns is misguided, if there's something better I can do, or if I'm fundamentally against the mission of FBGratings too much with what my aim is. Ideally I'd like to have something driven from your data which can be used in all modes of the game, but if that's not possible then I won't worry about it.
