Dave,
>Impact is very short. It is about a half a millisecond, or 1/2000 sec.
Edgerton's photos show total duration of ball contact with the clubhead,
using a 100 compression Spalding Dot golf ball, was .0004 seconds.
Compression was .0002 seconds and decompression was .0002 seconds. Is
impact time considered to be just to the point of total compression, or the
time until the ball leaves the face of the club?

Hey Bernie,
How's it going.
I would expect that with today's higher cor drivers and different ball construction that "impact duration time" has gone up a bit.
I wonder how much that would matter.
David
