The rules state that timing starts from selecting the level, but I think it should start a little bit later. The best starting place would be the moment the banner displaying the objective appears (as starting time when the A button is hit or something may be difficult to discern for Gunship players).

This is because, under the current rules, every time one makes a mistake in an IL speedrun and want to reset, they'd have to find a way to get back to the level select screen. And the only way to do that is to either finish out the mission (which could take awhile if the mistake was early), or pause and quit back to the Nintendo Land plaza, forcing them to re-enter the game, select a Mii, etc. If we start the timing from the banner screen, however, then all one would need to do to reset is to pause and hit "restart."

I'm willing to help retime the existing runs if necessary.
