Presumably that + is for up to 1G mersenne.org limit, or 1169M max of AVX512 prime95. Or would it apply all the way up to say OBD (3322M)? Is the optimal proof power an output of a straightforward function or does it require empirical testing to determine?

I didn't worry about OBD, it looks like the next transition will be near 1600M.

Looks like about every 2 bits on fft length is +1 on proof power. So (extrapolating in Mlucas fft lengths) that would imply power 12 would be sufficient to ~6.2G, ~1.87 Gdigit, not something of concern for decades or centuries.
