~p2.45, about a century for M(82859933) from a very long extrapolation made from only 3 data points and limited precision.

What I've seen for other codes range from 2.03 up. 2+ is the minimum, One for iteration count, one for operand size, plus a bit of change for fewer bits/word in the fft transform at larger sizes. Or n * n log n log log n. CUDALucas 2.094, prime95 2.094. https://www.mersenneforum.org/showpo...78&postcount=2

(Folks in the know, don't take that as talking down to you. It's for those looking up at the learning curve still ahead.)
