You're still getting the point. CAP data is a heuristic which sometimes is good sometimes is bad. Not reliable. In my evaluation i try to not rely on that kind of heuristics too much if i do i lose bigtime. So is capdata. You rely on it and lose, or you don't rely on it and don't lose. It cannot 'guide' you in any way. The only thing that can guide you are the newest editions of grandmasters and some insight how computers perform. Whether a computer is unhappy or happy in a position doesn't matter, as long as it produces the right moves. If your program is 2000 rated, then CAP looks great. if your program is trying to achieve a bit better as that, then you can't use CAP data. I guess this is the basic problem. You don't even get close to 2000 still with your insight, yet you're creating a book for programs which have past that border a long time ago. Every chessplayer who plays national competition (1800 and up in netherlands to use a rude number, some teams are way above that not to mention masterclass competition where this year my team didn't even qualify for) is laughing like hell seeing the outputs of the CAP data.
