I propose we change the method of timing for all categories to start when the "Gate 1" text disappears (such as with the 11-20 category). I don't see any good reason why timing should start on the Mii selection screen instead of there.

Requiring that timing starts on the Mii selection screen significantly increases the time taken to reset. Since it's faster to start from the "player setup" screen accessed after the game ends, all speedruns would ideally start there. This means that, in order to reset, one needs to intentionally lose all their lives, which takes a lot longer than just pausing and hitting "restart."

Changing the rules like this would not invalidate any of the already submitted runs, it would just require them to be retimed. It would also make resetting much easier.
