Is it because there was some "chicken wing" motion with the elbow drop? That's a common affliction and one reason why many people prefer keeping their elbow and shoulder still during the stroke.
For those interested in this topic, see the list of disadvantages on the elbow drop resource page.

There was some slight side motion (It doesn't take much to throw you off) when he dropped his elbow and when his shoulder moved but his accuracy increased as soon as he stopped dropping his elbow. It's fun to see someone improve almost immediately upon such a slight correction.
Are you still selling those DVD's that cover this type of information and much, much more? Where can someone buy your complete set of DVD's?
