We have also found that using negative Contempt reduces the elo deficit for Komodo against Stockfish, perhaps even by more than it should based on pure math. I suspect that Komodo is relatively stronger in the endgame, so negative Contempt tends to produce more trades and more endgames.
Komodo rules!
