Who was talking about the position of the elbow at impact? I stated that most PGA tour golfers have their clubshaft on the elbow plane at impact. They get it there by having their clubshaft shift planes from the turned shoulder plane to the elbow plane during the downswing.
12-1-0 and 12-2-0 recommends a zero plane shift swing where the golfer remains on the turned shoulder plane. I cannot understand why having the clubshaft on the turned shoulder plane in the late downswing and at impact is deemed to be desirable.
Thanks, Jeff. With regards to Plane Angle Variation (Component #7) -- and making a mental adjustment for camera placement, especially in Tiger's case -- what conclusion(s) do you draw from these photos?
I only know that there are significant variations in how golfers look in their late downswing. There are golfers like Toms/Furyk/Hogan who have their right elbow tucked well into their side with a significantly bent right elbow at impact. Then, there are golfers like Tiger Woods who lets his right elbow move well away from his right hip pre-impact and that causes his right elbow to be be straighter. TW has less plane shift than DT.
In general, I think that most golfers have a shallower clubshaft plane at impact than the angle of the TSP.
See the next photo.
I have noticed that most professional golfers, irrespective of their end-backswing clubshaft position, tend to shallow their clubshaft angle in the downswing so that they reach the delivery position on a shallower plane - roughly 45 degrees (+/- 5 degrees). I generally never see professional golfers coming steeply down the TSP line.

Jeff out of this list ..how many do you think have no funny business going on trying to be on the elbow plane and how many are on a true elbow plane through the business end from 9 to 3 ( impact zone )
