[O.B.Left]

I am talking about the loft of the face increasing during the impact. In every one of those irons shots, it is quite visible that the face is delofting upon impact (even the lob shot). Sure a bunch are miss hit and they also rotate.

Because the ball is going up, the face must be going down.

Where in 2-c-* is the CG of club head mentioned?

I can't find it.

Don't get me wrong. I am not saying hinge action can't happen.

Saying that the clubface is adding loft during impact is all I am discussing.

Interesting point but does that necessarily discount the net variances? Layback only vs closing only given the delofting you mention. There must still be a difference no?
