Auto-Green
Does Auto-Green add rhythm to my shot?
No. Auto-Green is timing only: it holds Square with the right stick neutral. Button Rhythm is the mod that adds tempo.
No. When you click R3, the script holds Square for the value's milliseconds and releases it with the right stick held neutral. It is timing only and never performs a rhythm sweep.
Tempo on button shots comes from a different page, Button Rhythm, which pulls and flicks the right stick at the output level when you press and release Square yourself. Auto-Green and Button Rhythm are separate mods with separate values.
