So I’ve seen it officially stated that your overall rank is always used, and that the individual category ranks (such as 13 x 13 correspondence) only have informational purpose. I don’t think this is true, however.
In ranked games with automatic handicap/komi, it’s happened to me a lot of times now that, for instance, I’m playing someone whose overall rank is lower than mine, and they still get white with reduced komi. The reverse also happens - their overall rank is higher than mine, but they get black and handicap stones. I think this is because the site actually uses your individual category rank to determine handicap/komi. Here’s a current example in which I think this is a likely explanation (13 x 13 correspondence rank used to determine automatic handicap/komi): https://online-go.com/game/10680158
Now I’m not complaining - I actually like that system. It’s just that it has been officially stated that only your overall rank is ever used, and based on my own experience, this is simply not true. Could someone clarify, please?
