Meteor cancel windows are an attribute in PSA.
Most people probably think or have been told that the meteor cancel timing in brawl is 25 frames. However, it turns out that this is not entirely true for all characters.
After X amount of frames of hitstun from being sent downward, you can meteor cancel.
Longer than usual window: Charizard (30), Meta Knight (32), Pit (32), Wolf (60)
Shorter than usual window: Ivysaur (15), Olimar (15), Yoshi (20), ZSS (15)
Everyone else: 25
For PSA users, attribute 0x05C is the meteor cancel frame.
Sucks to be Wolf doesn't it?
I use it to give all my PSAs better windows.
