Sportz - as mentioned a lit earlier I took the closing prices on offer at both Betfair and Sporting Odds and applied a Dutch Book to the first five favourite with each of the two betting agencies. They both had the same five horses in the same order but with slight varying odds. I just did it as a reference to how we performed as against the betting market.

As an aside, using the market as a tool for Dutch Booking It a way of making money if the right races are picked, but I mean the right races.
