I cannot reproduce this problem. Has anyone else seen benchmarking issues with build 15? Does the hwloc output in results.bench.txt look reasonable?

I can add this (probably will) but it is a semi-worthless feature.

Say you ask Pfactor to find profitable bounds where a factor saves 50 LL tests for exponents around 100K and 10M.
Well a 100K LL...

Yes.

I think gpuowl automatically tries smaller proof powers. I've added that feature to my prime95 to-do list.

axn is correct that optimizing bounds to maximize saving PRP/LL CPU time is different than optimizing bounds to find as many factors as possible in a unit of wall clock time.

If Gerbicz error checking fails (detects an error) the PRP test backtracks a bit and proceeds onward.

I am very curious why the default implementation of 300K FFT is so poor on your machine.
