By level 89 and you still have not chosen a specific ball to play yet choose to experiment with different balls - is that logical?
This could explain your scoring - do you know the distances of each ball you use? I guess not.
Failure to use one type of ball is illogical IMO. If you really want to improve, get three decent wedges, dump the hybrid and stick to one ball and map it using different spin....then do not run out of that ball.
