Effect of differential on a bowling ball
« on: October 01, 2009, 04:07:51 PM »
I read somewhere that the maximum allowable differential on a ball is 0.80.  I read the definition and understand that it has to do with maximum allowable track flare, but I don't know what that means.  Can anybody please explain?

I think it used to be 0.08, but now it's 0.06

I think higher differential is related to higher flare because of how much "clean" ball surface touches the lane, which allows the ball to have more traction. Don't quote me on that, I'm not a ball expert and don't mind being corrected lol

In addition to what has been said, I like to think of differential as a measure of the ball's "stabilty" once it encounters adequate friction. The higher the differential, the less stable the ball may be later on the lane.

This can be a good or a bad thing depending on the bowler's attributes, lane conditions, coverstock finish, and several other things that impact ball reaction.

The effect of differential on a ball is this: The more differential a ball has, the more flare potential the ball has.

 A ball with a .06 differential has more flare potential than a ball with a .03 differential. Doesn't mean it will HOOK more, only that it has the potential to generate more track flare.
