When I've looked at these losses they were due either to bugs, or to bias in the playouts, for example when there is a semeai. The program will think it has 80% win rate when it is actually already behind.

If this leads to a loss, I think that should happen only when there is some consistent bias in the tree that misevaluates some part of the position, and that imposing the komi *might* in some specific cases patch up the deficiency, but probably won't have big impact in general case. This is good experimentation subject though.
