random,
an easy way to clear that up is to allow the lead elbow to fold BEFORE it pulls away from your body, this is why hogan did the half swing drill with his elbows glued to his sides
A very effecient way to swing is in the back swing the rear elbow folds while being close to the body and then after it folds it pulls away. This keeps it from flying too much
then on the downswing the front elbow folds close to the body and after done folding pulls away
