I don't think the particular limit matters that much. you can limit it to 2, or 3, or 4. I'm not sure there is anything to be gained by doing it 2, 3 , or 4 times? time out or you don't? they get a lot more meter than you do when you do it. Maybe stall for gaining vorpal?
I guess it would be better to make it low so it's immediately obvious and the other player doesn't have to be look.. 3.. 4.. Ok that's illegal!
Do 1 under the legal limit, other player jumps the gun and pauses, gets DQd?
Lol.
