Your three-quarter swing is longer than you think
PorzakGolf has the player make what he thinks is a three-quarter swing and points out the lead arm still finishes higher than the shoulder - meaning the arms drifted a bit beyond the turn. His takeaway: what feels like three-quarter is longer than you think, so feel a three-quarter position at the top of the swing all the time, even on full swings.
