How extensive?
 

I do not know how advanced this question is but it does seem to be a incubator type question. Does extensor action contribute to radius power by extending the radius to its max? EA has the effect of "lengthening" my left arm 2-3 inches. The structure it provides also helps resist deceleration at impact?

I'd say yes and yes. It also seems to add effective mass to the blow and easy power. To say nothing of consistency.

In my incubator is the thought that it also discourages the bending left wrist by promoting an on plane thrust post low point. A thrust at the plane line rather than an up and in (the path of the hands), false feeling of target ward thrust per 1-L-15. Drewit, how am I doing here? Needs more incubation time, I know.

Taking out the wobble
 

You are doing excellent, but it may not be safe to mention me by name (whatever name that is today). Mike O is big on guilt by association.

O.K. but pray tell who is Mike O.? Dont think Ive heard of him or Bucket for that matter.
