I think the big komi is an anomaly with very small boards, where white player can't even live.: 1x1 : Draw, because no legal move (or losing points allowing suicide) 2x2 : Draw, both with super ko rule or simple ko. 3x3 : B+8 (japanese rules, chinese B+9) 4x4 : Dificult, but I think is a draw with japanese rules 5x5 : B+24 (japanese, B+25 chinese) 6x6 : Probably white can live and black wins but less than 24 points Bigger than 6x6 looks like 8 or 9 is near correct komi for odd boards (7x7, 9x9, 13x13, 19x19 etc.), but I suspect it will increase very slowly for bigger boards (much bigger than 19x19). I believe that small boards are not representative, because odd numbers are much better for black than even numbers, and because when white can hardly live, the bigger the board the bigger the territory black can take. Five points of komi on 19x19 looks extremely low, more in the 7-10 range.
