The 4 factors on the RDSS2 sup line score are variations and or Ted's "home brew" of the 4 basic
Sartin supplementary factors.
Sartin Pace Number ,
Fx - which is the same as the FX on the primary factors
Entropy and
Total Pace Potential
The factors you see on RDSS2 are comparable,to what was on Sartin programs like Val4.
Ted just "rolled his own"on RDSS with the names and took away the repeated FX
