[O.B.Left]

The reason asked for clarification of angular speed is Im lead to believe it is the straightening of the R/wrist bend at or just after impact,now I can remember somewhere in the book that this is ok so long as you have educated hands,I will find it,but is this correct ?

IMO angular speed is not the straightening of the right wrist bend, aka throwaway definitionally.

Here's Homers definition from the book ;

This involves Angular Speed which is measured by the number of degrees of an Arc through which the motion moves per second.

The quote you're looking for might be in 7-19 Lag Loading where Homer talks about how a thrown clubhead will not ruin the shot if the ball is hit prior to the clubhead passing the hands. Im paraphrasing here.

Obviously, if the thrown Clubhead doesn’t pass the Hands until after Impact Fix Position (7-8 ) is reached it still complies with the Law of the Flail (2-K) but precision Timing and Clubface alignment becomes difficult and, however widely used, is still an essentially perilous deviation.
