I don't think I have the necessary hardware to capture the display and time it that way, so I was wondering if the mods are able to time it themselves. PS: I'm recording off my phone

Time runs the same that you would on a SNES or emulator. Timing starts on the frame mario appears (2.2 seconds after you click 1 player game) and ends when either the category says it ends, or on the frame that peach appears.
