I'm not being critical of this style - it's perfectly feasible to just upgrade often and keep up in this way.
I agree with what you say. I think the main reason why, say, level 30 is currently only marginally better than level 16 is that the life-and-death search doesn't scale as written. The other reason that a program with no global search as GNU Go will always suffer from some systematic evaluation mistakes that won't go away no matter how deep you search in the local fights. E.g. if GNU Go doesn't get it that a dragon is weak and needs defense for strategical reasons, it won't get it at level 100 either (as the analysis for that is mostly static). Arend
