I was just going by the 40% increase in position players and more than double increase in pitchers. But, if you compare the final numbers to the eligble under 10 year only, pitchers are still a little short by comparison with the lowered requirements. I don't think there's any way you're going to make everyone happy but I, for one, am not interested in filtering thru 480 players right off the bat. And, if they're never going to "disappear" from the nomination screen unless elected or failed to be elected after 5 nominations, the number will get unmanageable really quickly.
A couple hundred after 10 seasons sounds about right. 20 per year more or less.
