Nice, thanks for the test I actually didn't to any FRC/Chess324 testing so it's nice to see that the expected gains kindof match normal chess gains

Yes I think in these conditions it is around +20 Elo which I think was around about what you were expecting for normal chess at a fast time control.

Actually I just ran an Ordo calc, it has a +24 Elo performance over Clover 6.2
