I think I kicked it.

I try to do backcourt as though I'm pointing to one side of a line, and then the other side, so I leave my palm more or less downward, and just move it in a slightly arching motion, using a lot of horizontal. I do carry more up and down with the palm facing up and hand moving straight up, and then flip hand downward and move it downward. not much horizontal, mostly vertical. This makes it easier to tell the difference.

I was sorry I did this last week when I made a very,very bad backcourt call, and I wished I could have said, "No, no, not backcourt, I was signalling a carry!" But the mechanic made it clear what I was calling, which was without question, wrong.!!!
