Until i set Experience MuliPV = false, [eman experience] altmost learned nothing and unnecessarily lost a lot of games.
Due to Experience MuliPV = true, [eman experience] lost during 400 games to understand that it don't know how to win with Ra8-b8.
- Here, scid showed Bc8-d7 was the bestmove as black. [eman experience] had to try several moves until it finally learned Bc8-d7.
- With Experience Multipv = true, eman wrote tons of moves and some with very low depth into the experience file. Here, with Experience MultiPV = false, we would have seen only 6 or 7 moves in the experience file.
In the case of a tourney, Experience MultiPV = true is more usefull because Eman won't read thousands times the same experience data from the same position (2 times per round, at least 1 time as white + 1 time as black).
In the case of learning an opening, if at each position Eman writes non-played moves with low depth, in the end the experience file will grow unnecessarily and slow down the learning so it lost more games.
