Depends on what ball.With modern high performance balls,it is well within reason to expect them to need resurfacing well before 30 games.Mid and low end equipment will generally keep their reaction longer between surface maintenance.

Here is a video showing how much the surface of a ball changes during three games.  A ball with a rougher surface will change faster than a smoother ball.  The ending grit that a ball will stabilize at depends on the surface the ball is rolling on.  Ex. A wood lane will be rougher than a synthetic lane.

OK, thank you! I have a good idea but this is kind of hard to believe. Why would they use such a rough finish( 500) that will change quickly? From 500 to 1500 or even 2000 in 3 games? Wouldn't we have to make a move every 3-5 shots?

Almost any ball can claim to be a super hooker if it had 500 grit finish( that holds up). Shouldn't a "real" hooker have 2000 or even finer grit? Didn't the Storm Virtual Grivity have 4000 factory finish?
