Just gonna add my hand-written, poorly-organized results to the fray, just to offer some help if I can:

300% for offensive linemen proved to be too much for me, except for centers, as only 10 centers eclipsed 85 overall, and none made it to the 95-99 range. Also, I tried 250% for wide receivers, but that seemed to be a bit high (even though it's cool that 3 receivers got over 95 overall). For the rest of the results, check them out on the imgur link, and I forgot to include the base ratings at the start in the hand-written chart, so my bad on that one. Hope this helps TDawg out, even in the slightest way possible
