I've read that the USBC changed the limitations on differential since changing over from the ABC.  Several years back ABC changed the limitations on the coefficent of friction (COF).

How does the COF change between Lane 1 equipment and how does it effect the bowling ball's reaction to the different lane conditions?

I know there is COF differnce within every bowling ball company and not just Lane 1 specific and its the same concept.

I think they changed the COR (coefficient of restitution), not the COF.

"the ratio of the relative velocity after impact to the relative velocity before the impact of two colliding bodies, equal to 1 for an elastic collision and 0 for an inelastic collision."

Or
how hard or fast the pins bounce away from the ball when the ball hits them.
