Here is a brief description of the key aspect/learning from Zig's skilltechnology that won the GOLF magazine award.

> "The X-Factor is the difference between the shoulder rotation and the pelvis rotation during the golf swing. It has been previously thought that it must be maximum at the top of the back swing. Cheetham's group after comparing experts and novices found that the actual increase in the X-Factor at the beginning of the down swing, caused by the initial rotation of the hips towards the target was actually more important than the X-Factor itself. Because this action causes an increase in the X-Factor they called it the X-Factor Stretch. It is believed that the extra stretch during the early down swing allows the upper-body muscles to contract more forcefully and hence provide more power to the down swing."

> I think this "x-factor" is analagous to Jack's THT at initiation or Peavy's "frontsidefirmup" (peavynet.com-this is not linear,however,as Peavy claims,it is the coiling/uncoiling or last bit of coiling before uncoiling which is a part of rotational loading and unloading,not much linear about it except how it realtes to blocking of weight shift).Also same thing Bobby Jones noted as the golden move in the downswing.

> THIS IS THE same move that the pro golfer Davis Love use to talk about.He maintained that he initiated an extra coiling move prior to his down swing that resulted in more club head speed.
