C24 is slightly worse against Leela and Allie, but clearly better against K, H and KMCTS. Scorpio/Stoof aren't stronger than K/H based on available data, so while we lack tests against them, I'd wager C24 doesn't lose elo against them. Overall, in RR format with 100+ elo weaker engines, contempt still helps to get on top.
My prediction for the rankings would be :
1. SF 2. Leela 3. Allie ; with K and H in 4/5 ; and Stoof/KMC/Scorpio in 6 to 8.
With the small sample size, Allie has an outside chance of going into SuFi. Allie's repo has not been updated since June, so I doubt it has gained a lot. But it is more likely that this would take out Leela out of SuFi than SF. I'm very confident in SF going into SuFi.
For SuFi, assuming Leela as an opponent, the plan is to go with contempt=0, as it seems to do better in h2h based on the (limited) data available, not trying so hard to go in positional struggles.
