Oh yes, that reminds me that when I discovered, thanks to another player who had experience with the AI review, that the “territory/score” option was much more useful (in their opinion, for 9x9s, and in my opinion too after testing it), the AI reviews began to be much more helpful and useable to me.
For myself, I found the “win%” option often not so useful (or at least potentially confusing/not helpful, because it’s entirely possible to play moves which lose “win%” well as a human, depending on one’s style) in various situations, especially on small boards.
(and perhaps it would be the case for many others or beginners)
I think modifying one’s play based on what the AI considers to gain/lose “win %”, may not work well at all for one, or help in improvement, if it doesn’t suit one’s understanding or style – and that “win %” risks being a lot more confusing/misleading than the ‘‘change in score’’ option.
It can also make some possibly very good moves (which are more or less even in terms of the AI’s "points lost/gained’’ analysis, look really bad.
For example, I have seen this in reviews in which 1 or 2 moves on 9x9 lose something like -25% for some reason, but are all -0.1, -0.2 -0.3, etc. moves when analysed by “points lost/gained” in the very late yose, with very little apparent difference between them.
And in general, “points lost/gained”, or “win % +/-”, and what is considered the best move/variation by an AI analysis, can also vary depending on the settings of the particular AI, the number of variations it analyses, etc.
So something one version of an AI analysis considers the best, but other AI analyses might consider inferior/bad, could be a bit misleading to beginning/inexperienced players, especially with large +/- changes shown for a particular move.
I wonder whether having the option default to “score” would be more helpful, especially for beginners or players who are still learning and play often on 9x9 ?
I rarely use it on ''win %" mode even when checking it myself now (after some more experience and experimentation).
Actually — apart from the clutter and overload of symbols, numbers and colours on the board, I wonder whether the “win %” default mode was also a large part of the cause of my initial confusion with the system, and the confusion that others express, or at least a barrier to learning to use the AI analysis in a way which makes sense.
(I didn’t know that the “score” option existed for some time either, and it seemed to be the case with other experienced players whom I chatted with who were confused by the AI review features as well.)
(I think “points lost/gained” option potentially makes more sense to a human’s perspective than the often large % swings the ''win %" shows for what are sometimes relatively fine/good moves, especially as a mode to begin using AI analysis for the first time with, and can potentially be more useful in many ways)
