Since I do lessons at GolfTec I get emails from them for various things, and I thought this was pretty interesting (not trying to shill for them or anything). But they did a study of over 13,000 swings and pinpointed 6 positions in the swing and compiled averages for those 6 positions for various handicap ranges. For example at the top of the back swing, the average 30 handicap has swayed 2.3 inches towards the target at the hips, where a pro has swayed 3.9 inches.
