In fact you can make first ultraplacebo encoding (0.1 fps) and make all the other encoding (with this analyse level) at ultra fast speed at all the bitrate you want. You can change all Rate Control level like you want too and I will test for AQ, deblock level, PSY (seem to be OK but perhaps that's refine is really necessary here).
I think this option will be really usefull if you want make test on particular option with really high speed encoding even for a complete movie.
and last but not least, with source in 1080p, the lossless source saturate my HDD with a little i5 3550 and I must choose SSD directory for lossless source. I can imagine that Ryzen 3700X can saturate SSD sata interface with 1080p lossless source with Reuse encoding.

For me gain in speed was from 10fps for UHD to 30fps for fast preset (just different bitrate).
Re-use at level 10. Rest default. Not sure how come you can have such a high gain (probably slow CPU +placebo preset).
