I agree with the OP that if this game were the “test case”, we would conclude that the AI analysis doesn’t have enough playouts to give a good indication of how bad white’s move 50 was.
The kata on my machine takes about 1.5k playouts (I mean, the number in the “visits” display gets to about 1.5k) before it has figured out that white J7 at move 50 is worse than -50%.
This would seem to indicate that:
- OGS Kata is using less playouts than that
- This isn’t enough playouts to give a good result
@anoek can you see anything odd about this one? Have we “turned down” playouts recently, or is this one just a wierd case for kata to work out, rather than indicative that the analysis is too weak in general?
