my position is that the way mark describes swing mechanics is NOT how mlb hitters swing nor is it the type of swing that includes arm action resembling the overhead/sidearm throw.
siggy's site linked by mark has the same info which is more fully developed by nyman at setpro and englishbey at his site. there are many devotees of this mechanical pattern on the net.
another one on this site who gets into the details of this "pcrw" pattern is Elliott, so another way to see how this swing is described is to search under elliott's handle here, 'ifubuildit'.
while this is not how I "see" mlb hitters swing, learning the pattern mark likes can help highlight the differences. it is always helpful to have multiple perspectives based on the natural tendencies/natural patterns you are influencing when you try to teach/learn.
