![]() ![]() I can't see much generic similarity in how PGA pros move their lead arm and club or the timing of their release. I can imagine JBH clubhead speed is superior to Rory at impact even though his peak arm speed is less. Look how fast Rory's lead arm is rotating compared to JB Holmes but their clubhead angular rotation at impact are pretty similar (JBH actually a little larger than Rory). ![]() I've been looking at these damn graphs for years and never realised how to interpret them properly until yesterday when I read this article below:Īrticle-KinematicSequenceTransitionDownswing.pdf (sgpl.ch) where the brown line moves above the blue line). more lag).Ĭheck out JB Holmes where during the downswing, the blue line actually moves above the brown line, which means he is increasing his lag angle in the early downswing but then they cross again at 'Release Point' (ie. If the blue line crosses above the brown line, that means the angle between the club and lead arm is decreasing (ie. Release occurs when the blue and brown lines cross where the brown line move above the blue line. ![]() So he's basically uncocking his lead wrist progressively faster than his lead arm (from a rotational perspective) from beginning of downswing all the way to impact (ie. The clubs rotational speed is greater than the lead arm but note that the distance between the brown and blue graphs (as the downswing progresses) gets larger all the way to impact. It's Jordan Spieth - 3 times major winner seems to be a caster all the way in the downswing (unless I've got this completely wrong myself- won't be the first time). ![]()
