0.5x A Presses / But First We Need to Talk About Parallel Universes - But first, lets talk about parallel timelines

Well, Flowey "Asriel" Dreemurr, hear me out.

A FIGHT press actually is made up of three parts

When FIGHT is pressed, when FIGHT is held, and when FIGHT is released.

Alt. When FIGHT is pressed, when the FIGHT bar is shown, and when you attack.

This makes one full FIGHT press

However, if one never attacks, then the last part is never counted for. This is what is called a "Half FIGHT Press" (sounds like a wrestling move :P)
