And the RG min and RG max is how the differential is calculated. As one can see on the Brunswick site, .053 is the diff (diff = track flare)

Take RG Max (2.610) and subtract the RG Mix (2.557) and you have the diff of the ball...and yes, this is how diff is calculated for every ball from every company.

Note: this is not intermediate diff found on asymmetrical balls.
