Please explain the difference between float and drag loading

[Yoda]

The Left Wristcock is not properly a function of the Wrist Muscles. Instead, it is the product of Right Elbow Bend (7-3). With Hitting, Right Elbow Action causes Muscle Power to Cock the Wrist. With Swinging, Right Elbow Motion permits Centrifugal Force to Cock the Wrist. Either way, there is normally no Left Wristcock unless the Right Elbow bends. This is true whether the Wrist is Cocked on the Backstroke or on the Downstroke.

With Float Loading, the Wrist is Cocked -- and the Right Elbow is further bent -- on the Downstroke. And this is accomplished with a characteristic 'gentle, even lazy' motion that does not disrupt the required Power Package structure. Herein lies the challenge: You must increase the Right Elbow bend (to affect the Wristcock) while simultaneously applying Right Triceps Extensor Action(to maintain structure).

Learning to bend the Right Elbow while simultaneously making the steady effort to straighten it is no small feat. But it can be done and is worthy of the attempt.
