All these patches are worthless if SF can not improve enough to beat Lc0... :( :(
SF keeps on improving and yet it can not reach Lc0 level... :o :o

It might be that elo gainers on one thread could add more on multiple threads. When SFdev was only +16 compared to sf10 on 1 thread the multicore test showed +23 give or take iirc.

Slim margins though.
