Ah, the tops were merely yesterday's symptom of an underlying problem.

As well as playing a shot at a time I have to learn to play that shot within myself especially for a follow up or scoring shot.

Yesterday my back swing was rushed ("subconsciously speed = distance") which means a) I lose control of the length of the swing b) My swing gets steeper, hence I suspect the tops.

Write 100 times on the blackboard. "I must engage brain before swinging"
