3 frames after Dave make full stop with his feet in "attention" there is a 4 frame window to hit A.

Pressing A early opens the switch kid menu without using the machine, pressing A late opens the menu after you're done with the machine.

After hitting A you need to wait 3 frames or more before pressing start.

Pressing start too early just means you have to press start another time.

This rules. i could never get this kind of data reviewing runs on VHS
