OK. Maybe my brain is not fast enough to recognize dwell time, but it is a major parameter for TW string data, so it must be indicative of something.
The difference between a really tight poly bed and user friendly gut is very noticable and would seem to imply longer contact times with a more resilient string. Correct?
My understanding of spin is that it is produced by the movement of the racquet while the ball is in contact with the stringbed in such a way that imparts rotation. The longer the contact, the more rotation should be imparted?
