A previous AW/CC said he separates 0-4 DP, P, and DNPs in several iterations via filtering and stacking.
The first filter = AAD & PME complete (which makes four stacks: has both, one, other, or neither)
The second filter = PME complete w/ Bachelor's +
and so on....couldn't believe it was that cut and dry for him. I think strat's matter more when you're going for 0-5 and up when the 0-4 promotion rate is like 90%.
