Fowlers left wrist is fully uncocked rigth after impact. Left arm and clubshaft is on the same plane basically. Combined with dual horizontal hinge a very quick swivel action into and past impact is needed. In theory almost infinitely quick. And together with it, a very quick and early overtaking is the only sensible consequence.

With a level impact left wrist and even a little wrist cock intact the overtaking will be much more gradual and this is the case with Hogan and Palmer.
