Now the real question is- if on the longer shots the face closes enough while the ball is on the face- to make alterations in the amount the clubface is open at impact fix for horizontal hinging, then how long of a distance is the ball traveling on the clubface/clubhead? And how does that integrate with the Golfing Machine concept that the ball always leaves at right angles to the clubface- i.e. that the return flow is so fast that the ball doesn't ride on the clubhead/face long enough for the down and out vector of the clubhead to influence the initial direction of the ball?

So ball doesn't always leave perpendicular to clubface, especially when the impact interval is long?

For a putter, as long as you have a square clubface, it doesn't matter how much inside-out or outside-in the clubhead path is, the ball will still go along the target line.

But for a driver, because of greater compression, it's not the same? Please explain in more detail Mike...
