definitions of "returned price" as opposed to "Starting price" or "final price"

[tolland]

Hi Chaps, I was hoping you might be able to help me here... I am trying to write up a system for a friend who insists that it is the winning strategy, and he got it from a guy etc... (I've done lots of these and forward testing usually proves a loser) Anyway the guy keeps going on about using the "returned price" of a horse, and I don't have much experience with horse racing itself, so I thought I would ask, as I can't fund much other than a few references to it on google. What is the definition of the "Returned Price", and is it different to the "starting price" or the "final price", and indeed whats the difference between the "final price" and the "starting price"? Many Thanks T>.
