Default LLR.exe FFT crossovers and iteration times

I've seen this asked before, so I ran some tests to try and find the FFT crossover points for LLR. I have narrowed the range of "n" down to 5,000.

Estimated FFT
crossover when
n=

40,000-45,000
60,000-65,000
85,000-90,000
125,000-130,000
170,000-175,000
210,000-215,000
255,000-260,000
300,000-305,000
340,000-345,000
425,000-430,000
515,000-520,000
600,000-605,000
685,000-690,000
815,000-820,000
980,000-985,000

Hope that helps
