Shore is actually a standardized measure of the hardness of the rubber, which
is only loosely related to it's shear rate.  Don't have the details handy, but
Shore hardness is measured by applying a standard force to a standard tool, and
measuring how far it sinks into the rubber.

And to make things even more confusing there are two shore scales:  Shore A
and Shore D.  Don't ask why.
