I think timing should start on first movement instead of clicking the start button because it avoids the load time and is a little clearer on when it begins.

also you shouldn't be allowed to start from the black start button in ILs because it's just starting from the middle of the game

edit: starting from the black button for new leaf and blossom in 100% should be allowed since by that point you would have already done bud

edit 2: please clarify when time stops for Bud because it says in the rules that it ends when the screen turns black but you stop your timer when the screen turns white

Fair points. Yes, it does seem better to start after the load, and the point about the black start button is valid too.

About the second edit, yes, it should end when the screen goes white. My bad, I'm going to go fix that.

Thanks for the feedback.
