i think it will depend on the shot and the approach, for example Jason has problems with synthetic lanes, he gets stuck, so he will proly slow down, but i would say he can easily make it 19mph

When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment
When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.
