Bernie, Rx+ is not a factor, it's the name of an Analysis screen. Compare that screen's contents to the Rx screen. It's the SAME, except for ONE thing - the addition of the BRIS Prime Power (BPP) readout.
All the factors on the Rx screen (and thus the Rx+ screen) are described as much as they can be in the
DOCUMENTATION THREAD, which I referred you to yesterday. BRIS Prime Power you know about (or can google more about on THIS site or others).
Rx+ is a screen which draws it all together, and also is the place where I will add new stuff.
Also, please Bernie - ask questions about RDSS in RDSS Forums. Ask questions about older Sartin programs ... in the Older Sartin Programs Forum. Doing it this way is a kindness and a consideration to other and future readers of PaceandCap who may be looking for useful RDSS info and would not think to look in a Forum dedicated to Older Sartin Software.
Thanks!
Ted
