I disagree. In my studies of 9x9, over a number of years, the human 19x19 rank generally carries over to 9x9. E.g. a 9p consistently beats a 3p, a 6d consistently beats a 3d, a 1d consistently beats a 5k. Whether they are playing at 19x19 or 9x9. (As an aside, my conclusion from this, which I personally think is very important, is that the main element of human go strength is shape, tesuji and life/death reading.) UCT programs are a bit different, in that (as they are "brute-forcing" in the number of legal moves) their strength does not scale up to higher board sizes in the same way human strength does. But no-one is claiming otherwise which is why people are referring to the 9x9 strength and the 19x19 strength of Mogo and CrazyStone as separate things. But, when we say Mogo is 3d at 9x9, it is fair to say that a human player with a 3d rank at 19x19 will enjoy a challenging game with it.
