The Jûrokubango has come to an end.

Over a long time, Black's Initial Self-Play Success Ratio (the blue line in the diagram) stabilised just over 50%. After the end of the Jûrokubango, it decreased by about 10%, still remaining in the "green" range.

We are looking at a viable solution here !

28b's surplus of won games in the Jûrokubango (the red line in the diagram) has reached the range above 0, while showing a strong upward trend.

28b has therefore mastered this variation just as well as 40b.

E.g. "A=19 // B=264" == Variation "A" was played in 19 games, variation "B" in 264 games.
(The labelling is designed for SGF-editors that label next moves with capitals "A", "B", "C", ...)
