A 30 point range within each negative PA range bracket seems quite wide to me, or are you suggesting this is inadequate? Regarding the development of players, strictly after a PA has been set by the game via the DB, I certainly agree more variation is desirable. We actually did quite a lot of work on that this year (FM17) to hopefully enable a few more Balotellis, Ravel Morrisons, etc. In other words 9 times out of 10 they waste their potential, but that one save they become world beaters.
