Dog Pat Technique

A Verdasco video

Did a comparison of Verdasco and your student, at the momemt immediately before they begin rotating their torso.
I can thing of three things which might cause your student's racquet edge to point further than Verdasco's -

1.upper arm has internally rotated further
2.forearm has internally rotated further (ie. pronated further)
3.your student has a more extreme grip

My guess is it's the forearm pronating too far (#2), based on looking at the position of the thumb relative to the "inside" of the elbow. Also the top of your student's hitting hand is more visible. The upper arm position looks the same. Not sure about the grip.
In my opinion there really isn't much difference in the timing. Your student just seems to twist the racquet further during the takeback. Watch that they both "open up" the racquet (i.e. externally rotate the arms) when they rotate their torsos.

Was a Verdasco still picture taken from a stroke Archive?
If yes what is a link?

yes it was...can't remember which exactly. Anyone of the neutral stance forehands taken from a side angle should be comparable.

10s, you're right. If he has time he can produce a bazooka of a shot relative to his size and body weight. Under pressure, he makes mistakes...also on wide balls he experiences problems.

The dog pat seems to cut his loop short. He prepares well, goes into his backswing, but flattens the racket face at the critical point as he commences the forward swing. The bottom of the loop somehow doesn't happen.

The probems is how can I rectify this rather deep rooted problem?

You mention trouble under pressure and on wide balls. Are these mostly due to hitting long, then maybe some in the net attempting to avoid hitting long?
