yeah, sts, you're right.. i think people who are better at one combo tend to lean toward the patterns of them
The 'neither' category is for everyone else that doesnt have the pattern sense or people who dont 3-wide/4-wide. some people may be a hybrid like a 3-wide/4-wide but theyre not in the neither group though (e.g. qmk). some may be neither in a way because they still combo through 2 wide (e.g.shizi?, candyman) or there may be people that are fantastic downstackers but their ability to downstack is mostly balanced out by the combo/t-spin ability of the other player (e.g. anon, johnny). And every style that wasnt mentioned would fall into this group.
