So lets make 2 hypothetical races with Beadman and Cassidy and Evans the only riders.
Beadman rides the Evens favourite in both races with Cassidy riding the 6/4 shots and Evans has the 9-1 chances.

So this is what it can all boil down to.

BCE 40
BEC 10
CBE 33.3
CEB 6.7
EBC 5.6
ECB 4.4
for each of the 2 races giving us 36 permutations.

After going through the 36 combinations,in this case the Jockey Challenge price is the same as the price of the starters.

Does that seem right?

Tell you what I did learn but!
If you can't work out whether you will be getting value on your bet,DON'T BET!
