Newbie needs clarification!

I am new to RDSS software and have few questions your help would be greatly appreciated.

1. In RDSS are the races divided into three equal parts (F1, F2 and F3) or if F1 = 2 furlongs, F3 = 4/6 Furlongs and F3 = 4/6 Furlongs to Finish Line?

2. I am looking for a simple explanation for Factor W or Factor Win and Factor X and how you should use these factors when evaluating contenders? Listed below is what I was able to extract from reading the Follow Up.

3. I notice when I was evaluating the races in the Demo database DC and
VDC ranking produce some nice price winners. Is my explanation below of the two correct? Do you have a simplified explanation?

4. Is Total Energy a good indicator to identify the pace of Sprint races?

5. Is CPR a good indicator to identify pace in Route races?
FW: Factor W or Factor win (EP + SP) is the balance between Early and Late Energy-Velocity yield. Different formula for Sprint and Route is particularly effective when a horse runs a balanced race. (In RDSS, FW in sprints = (2x EPR)+LPR. In routes, FW = EPR + (2x LPR)).

FX: FX: Factor X is the weighted composite of 1^{st and 3rd fraction velocity or energy expenditure. (}The MPH FactorX (F1+F3) / 2 = RDSS FX = F1+F3 (same thing)). This factor is only significant in sprint races. My Opinion: it works for Sprint because it gives an indicator if the horse can carry it speed to the finish. Factor X, which is indeed the first and third fractions added together and divided by two.
DCL: Deceleration (F3/SC) – Deceleration is simply the ratio of Fraction 3 velocity to Second Call (SC) velocity.

VDC: (Velocity relative to Deceleration) is a fraction by fraction summing of deceleration relative to how fast the horse was going in that fraction, then ranked and merged with the Bottom Line ranking, such that you could have ties if the BL rank was lower but the V/DC rank was higher. Guy (and lots of others) were troubled that you could have ties in a factor ranking, but Doc wanted people to look at horses who did well at overcoming the pace of the race, even if they ranked lower on BL/BL which they would often do if they happened to have a lower Total Energy. If odds permit, such horses should be strongly considered for some kind of a wager.
I have seen stats from a several data keepers (Froggy comes to mind) who report that Top 2 and tie V/DC ranked horses win about 65% of the time, and Top 3 and ties 80%+. Of course, it varies by track, distance surface, etc. In my opinion, everybody should consult the V/DC rank in their analysis.
