DeltaLover, sorry for the delayed response (I am off recuperating from a surgery this week and next: can't type very well or very long).
I will respond in full to your questions in a future thread in the Handicapping software Forum, as soon as I can. Meanwhile, there is an entire website devoted to the
Sartin Methodology and the details you have requested - though the answers may not come as succinctly as you prefer.
For now, your points:
2. Daily Track Variant (DTV) and Inter Track variant (ITV) supplied by TrackMaster.
3. Distance to Distance adjustment table, tweaked by ITV.
Points 1 & 4 require more elaboration. As soon as I can.
Thanks!
Ted
