One other thing to point out, that may go back to Markus' original intent:
Players MUST lose talent in OOTP. If they didn't, the leagues would grow more and more talented over time. Every player would just keep getting better and better.
So, in the engine, there HAVE to be checks and balances. Much of that IS associated with injuries and aging, which is, I think, largely how it should be. (This is compared to previous versions like OOTP 6 wherein it was almost entirely random.) I think there is room for continued refinement in that algorithm. (There's a conversation going on over in the beta forums about this right now.)
I DO know for a fact that at LEAST the impact of day-to-day injuries on ratings has either been eliminated entirely or drastically reduced. And perhaps we will find that with OOTP 11, that was enough to move things from "unacceptable" in the minds of people in this thread to "acceptable."
But, I can't claim to have run any tests to prove those results one way or the other. Unfortunately, as Getch intimated, it's not an easy thing to test at a statistically-significant level.
