left elbow at impact
 

is the left elbow at impact down or pointing at the target at impact?

I'd say it should rather point down, otherwise it would be difficult to keep the club on plane through the shot.

Elbow at target would make it difficult to square the clubface at cause blocks to the right if the club path is in to out.

take a look at Hogan on the cover of 5 lessons. His elbow points at the target!!!

Its down don't try to point at target you could hurt your arm, on the cover i don't see it pointing at the target
