That's the point isn't it? So why should the NPS increase as the laziness decreases? My guess for the reasons: In the opening there are not many tactics that win material, so although the positional score range is small, the lazy eval can't kick in very often, since the material balance nearly always comes in equal. In the midgame a lot of lines can use lazy eval because they are either way ahead, or way behind materially, because of the tactics. In the endgame, i'm not sure. Endgames do have a lot of tactics, sometimes even more than the midgame. But maybe that wouldn't be enough to make up for the really huge positional factors you have to allow. Could it be that Crafty can do the endgame postitional eval really fast, compared to a midgame positional eval?
