As a very rusty Shodan, if that, my ability to judge the reliability of the data being generated is limited, so I really appreciate feedback!
If indeed J7 is sente, and not an overplay, is this because it is splitting the various black groups? The FBS algorithm's first guess is that the lone White stone peaking out at J5 (K5 being totally blocked off) is rather out-numbered, at present, and that the split groups are both fairly healthy. Some prepatory moves could raise the viability of a J7 play. In fact, the highest recommended move, L13, is deemed to improve the J7 rating slightly.
One thing I'd like to see is if known sente points could be fed to the Full Board Strategy component. And, if known boundaries of groups could be integrated in a meaningful way.
How much improvement is necessary (and what would it look like) before the recommendations provided by this sort of component becomes helpful? I assume "usually reasonable" full-board suggestions are better than random choices, if they can be derived at a minimum cost in cpu's, and they can be overridden by the more precise local reading algorithms.
