well, my issue is this: what sense does it make to have something called a "possession penalty" when the penalty is only happening because of FGA. If a player's RL usage is 25% and what he does in the sim is 24-26%, he shouldn't incur a penalty because those possessions were more FGA (and almost always, turnovers) than fta. I would say that the penalty is fine, but with all of my testing over the past year, I've determined that I believe the penalty is too restrictive.
And the double penalty of team & individual has always been dumb. The principle with which they explained it makes some sense, but if you just have the individual penalty it accomplishes the same thing.
I gave up trying to convince admin of anything years ago, though. I also gave up on giving them money.
