Question re resurfacing.
"The circumference of a ball shall not be more than 27.002 inches nor less
than 26.704 inches, nor shall it weigh more than 16 lbs (no minimum
weight)."

Roughly speaking, and I know it depends on how much of the surface layer is
removed each time, how many times can a ball be resurfaced before it no
longer meets the minimum diameter requirements? Also, why is there a minimum
diameter requirement. I would have thought that the smaller the ball, the
worse it will perform when hitting the pins as there is less of it to go
around.
One answer to a previous post of mine regarding serial numbers stated that
the engravings/etchings on a balls surface can be thought of as "wear bars",
similar to car tyres. Is there any kind of standardisation of depth for ball
markings?
TIA.
