At GolfTEC, a part of the swing that we measure is Hand Sway. Hand sway is a measurement of how far the hands move laterally in the golf swing on the backswing and the follow-through. The tour pro's that we've tested have a hand sway measurement of 47cm from their starting hand position by the time they stop at the top of their backswing. Most of our amateur clients measure between 20 and 35cm of hand sway.

The average tour pro's hand position at impact is 17cm in front of where their hands were at the address position. This is an indication that the pros maximize the lateral motion of their hands in their golf swing creating more distance and straighter shots. This also indicates that their shaft is leaning forward at impact. Most amateurs' hands at impact are 5cm behind the position they were at address.

BLACKYDOG---- I SUPPOSE THIS WOULD INCLUDE THE SLIGHT LATERAL MOVEMENT OF THE BODY ALSO, BUT IF I AM READING IT CORRECTLY IT SEEMS TO BE LEAVING YOU OPEN TO SLIDING ONTO THE OUTSIDE OF THE RIGHT FOOT IN AN EFFORT TO MAXIMISE HANDSWAY.
