IMPACT...The Moment of Truth! (July 2007)
Chuck Evans - Executive Director of Instruction - Medicus Golf Institute
A lot of players and teachers think that the clubface should be square at Impact. Nothing could be farther from the truth! The ball DOES NOT LEAVE THE CLUBFACE AT IMPACT!
In fact, the ball actually compresses on the face up to 30% of its original size and stays on the face up to one and a half inches after Impact before it leaves the clubface. The bottom line is...don't be concerned about the face being square at Impact. In fact, the clubface should be slightly open to allow for the closing of the face and the separation point of the golf ball.
