Does the official clock start on player input, or is it purely in game clock? As I'm sure some have discovered, you can back up on stages without triggering the in game clock, allowing you to improve your speed at the beginning beyond what would otherwise be possible. I'm just wondering if exploiting this is something thats within the rules.

Maybe it's allowed but not glitchless?​​​ not sure if it's a glitch tho.

Thanks.
