Blake's description of impact as being a feeling of "collecting" the ball (he likened it to a catapult) and its remaining in contact with the clubhead over a period of time is not the conventional wisdom or what science says about the golf swing. Rather, high-speed photography demonstrates more of a pure collision of club and ball at impact. Impact duration of a high-speed golf swing has been measured with time ranges from about .0004 to .0006 seconds, virtually instantaneous even though the ball compresses, rebounds and jumps off the face during that short time. After release, the golfer's effort is no longer affecting the club, ie, the clubhead is, in effect, a freely flying object when it impacts with the ball. That feeling of "collecting" the ball is just that, a feeling--the feeling of a well-struck shot.
I am not familiar with the book you mentioned, though I would think you could eventually find it with an iterative Google search. SD
