My best so far is 4017 PQP for $1415.95 (284% efficiency, or $0.352/PQP) on a MNL-IAH business class sale fare on TK that popped up a couple of weeks ago on the Premium Fare Deals board.

I'm planning out my travel for 2020 taking the new requirements into account, but I'd never do a PQP run this early in the year. There are just too many variables to know whether or not I'll need/want extra PQPs. I'm also not sure I see a ton of value in doing a TPAC PQP run in Y. I value status because it helps me avoid Y on longhaul flights... I'm not sure I'd voluntarily endure that on trip A just to get a benefit on similar, future trip B. However, to each his own, as far as that goes.
