Head lift @ BSW max
What it measures
Vertical rise of the forehead/head tracker at peak backswing versus setup (not driver launch angle). Face-on postural drift—often grouped with consistency reads next to the Lift and Turn trackers.
Units: inches
Why it matters
Excess lift often tracks with early extension patterns later in the swing and can change path and low point without you feeling it.
