Bill,
RDSS (and previous Sartin software using TrackMaster) does not use the Equibase SR per se, merely displays it. It uses the ITV and the DTV provided by TrackMaster, and it equalizes all pacelines' call times to today's distance using parallel time tables (as discussed above) and sprint to route and sprint from route projection/extraction formulas.
Tell your Dad, although the Equibase SR and the Sartin Adjusted SR (and TS velocity) readouts are on different scales, there should generally be some kind of synch in relative rankings between the 2. When there is not (as in Richard's last line), there's usually an explanation which might require various kinds of digging.
Cheers,
Ted
