For a swinger, it makes no difference whether its a chip, pitch, 3/4 swing or full swing. When the left wrist is loaded, there can be a 1/4 turn loading on the right index finger knuckle. No movement of anything, just a shift in the loading as the clubhead reaches the end of its arc. Ask John Riegger about how effective this is for Bunker Shots.
Along these lines, the right elbow is in a pitch position for swinging vs a punch position for hitting to accomodate the drag (via the number 4 accumulator) or drive (via the #1 accumulator) of the clubshaft and the associated amount of right wrist bend.

Bagger - I have seen those statements previously. I can understand the concept of loading the right elbow if one simply stops the backswing when the right elbow stops folding. However, if a swinger stops his backswing at that same time-point in the backstroke, is he also not loading the right elbow? Also, if a hitter gets a 90 degree angle between the left arm and clubshaft at the end of his 10:30 o'clock backstroke, and a swinger gets a 90 degree angle between his left arm and clubshaft at the end of his 10:30 o'clock backstroke, then in what sense are they loading the left wrist differently?
You also seem to be implying that a swinger makes that 1/4 turn loading of the right index finger at the end of the backstroke. Hmm! That is very different to Neil's suggestion that the 1/4 turn occurs during the start-up. Does that 1/4 turn involve a hand rotation, and does that hand rotation occur due to forearm rotary movements or rotary movements at the left shoulder socket level?
I was editing my post above when you posted. Don't confuse visible plane angles with hitting or swinging. Its very difficult to see the differences visually in shorter backstrokes. Elbow position through release is one clue and finish swivel is another.
The quarter-turn doesn't have anything to do with the startup swivel and the swinger doesn't "make" it happen. Again, there is no effort in "moving" anything.
The visual clues might make a good thread.
