I want to gain confidence in my models of SiC arresters.  Does anyone have independent sources of information on this modeling in EMTP-RV, or EMTP Version 3?

The example in the help section of Sic arrester (Sic90.ecf) give very good results compare to laboratory tests. You can extrapolate the value of the coefficient R in proportion to the nominal voltage of the arrester.
