To me, clockwise = down would be the intuitive setting.

I’m not saying that’s the “right” way for it to be, just a personal preference that either the devs share with me, or that the same devs believed most users would share.

As for why I find that intuitive, it’s probably because I associate clockwise with “forward” and anti-clockwise with “backwards”. In this specific scenario, “forward” would become “further down”. I hope that makes some sense.
