Reverse Max Damage Uppercut

Description
Like the Max Damage Uppercut, the reverse max damage uppercut is intended to combine a guard manipulation and star punch to ensure the star punch lands when the guard is up. Whereas a regular max damage uppercut is often used when the opponent's guard is down. The reverse is used when the guard is up.

in the video below, the 5th punch is a reverse max damage uppercut.

Execution
Throw a star punch, some time after the punch begins (this will vary depending on the fighter / their guard speed) tap up.

If done correctly, this gives the opponent's guard a window to drop, then come back up again after pressing up, just before the star punch lands.
