The risk of attaining that number will discourage most if not all players from continuing to plank. I would rather reduce planking to a minimum then have everyone do it as a method of winning.Putting a number on grabbing the edge does not eliminate planking, it probably reduces it, but it is still there.
That would defeat the whole purpose of what you're trying to do, because players CAN still plank.
Either way planking should not be banned as it is a strategy. As more players do it, people will come to learn how to overcome it.
How could you win if all the opponent needs is a percent lead and then just runs away like a *****? Just today my brother was using Captain Falcon against me and planked the **** out of me!!! I used every character and there was just no point. My brother doesn't play Brawl nearly as much as I do.
