What really matters?

[Psychotic Parakeet]

I need some guidance from you gurus here. I have been using Sartin Methodology since 2003, following this forum for nearly 10 years, and even had the RDSS software installed on my old Windows laptop a while back. I know there are some discrepancies with the program for Apple users, which is what I use now, so I had to create my own "Sartin" program from scratch using the Numbers program.

Anyways, long story short, but what factors and/or formulas really matter in deducing down probable contenders? I obviously have the classic EP, AP, SP, TT, FX, TTL, and E%, but I would like to add more to it, if possible. Are there certain factors that matter more at specific distances and/or surfaces? I am just getting back into the game, ironically it happened on Breeders' Cup weekend, and I am itching to go forward again.

I appreciate any insight, suggestions, and help you can offer me. Thank you so much!
