i would say that the mental game is the overall cause of holding back your average. with a weak mental game you struggle repeating strike shots. your confidence doesnt stay high, it can change from week to week. letting the lane play you, rather than playing the lane. self doubt and confidence issues will sink you for extended periods of time. otherwise, how can i go 2 months without missing a 7 pin then turn around and struggle to pick up half the next month? it eats at you and suddenly 7 pins are the devil that owns you. without confidence in every shot you make, be it strike or spares, your physical game is worthless. without confidence, your ability to repeat shots goes way down, as you feel the need to tinker with something, anything to right the ship. and by letting the lane play you, you fail to look past the problem and therefore cant arrive at the solution. that leads to worse problems, such as splits.
