Analyze your delivery and think about what you are doing when you practice. Feel your good shots when you make them and imprint it into your mind so that you can repeat them. Use visualization to practice off the lanes and go through the delivery in your mind making perfect shots.
Before any shot in competition, give some thought to what you are trying to do. Careless shots are wasted shots even if the results are temporarily okay.

If you are attempting to stay behind the ball longer to create an earlier roll,
try leading the ring finger through your target line. This will usually delay the
motion of topping the ball and or coming around the side of the ball.
