I suppose it depends on what exactly you try to boost. As others already stated doing just light playouts, no tree-search, AMAF gives a huge boost. With light playouts and UCT tree-search, AMAF still gives a considerable improvement. Maybe you can try to search the archives, I think I posted about it. My MCTS ref-bot has a parameter called 'useAMAF'. You can experiment with witching it on and off with different numbers of playouts if you want to. If I remember well, the difference was very obvious, even with high number of playouts. Also the latter statement I find an exaggeration. Plain UCT + AMAF + semi-light playouts beats GNUGo without too much work. All I needed was including some simple tactics and a few tricks to prune the tree early in the game (i.e. not play on the 1st and 2nd line).
