I couldn't find clear answers to my stupid questions on other forums, I hope Remi or Don, or someone else can answer here.

1) Is the distributed df-UCT implemented in some current Go programs? It is claimed that df-UCT move selection doesn't hurt compared to UCT, but its speedup (with the number of cores) is dramatically better (almost linear as compared to UCT(TDS) pretty logarithmic speedup).

2) What is now the value of an effective factor of 2 speedup in Go? I remember something like 50 Elo points, but I don't really know where to find data on current programs which use MCTS UCT sorts.

3) What is the computer score 6d against 5d? Or 5d against 4d? I knew of something like 80% for lower dan (2d vs 1d), but this could be off for recent bots. I mean in current rankings on KGS, not separated in time, the ranking there seems to drift in time. What are the scores of the current engines self-playing with handicaps, 1 stone, 2 stones?

Thanks,

Kai
