RanchWest working on a project Jack, no, my health has been such that I have not been up to maintaining results or databases for quite some time. I have had portions of this program going for over 25 years, so I do have some insight as to which factors are best.
All I can tell you is my opinion on which are best.
The odds line favorite wins a lot, but usually at low prices. On chalky days, it will usually have about 50%..
The BPPELO has a high share of winners among those ranked in the top 5.
S-Factor has been very impressive, but a little chalky. It does get some horses in the 3/1 - 5/1 range and a very few higher.
The others catch a lot of winners, but the three listed above impress me the most.
If you track all of the different Scott form factors, you can find some valuable information, both positive and negative. Especially negative. Many years ago I tracked 133 different combinations. Some were pretty dreadful. For instance, N0-sg was 3 of 83, 3.6% with an avg mutuel of $7.47.
These are all from the Odds, Speed and Form sections. I'd say the best prices come from Pace and Class.
