From 7/1 out to 75/1.....then withdrawn. Reduction factor of 8.3% applied by betfair. :shock:

Think they do the R4 by the amount of money matched and not the price of the runner

From my email correspondence with Betfair, they base reduction factors on what their estimate of a horses true chances of winning is, and then adjust them to correlate with the market prices. But obviously, they have to take into account and disregard market manipulation.

The only bad thing about this chart is that I missed it at 5.80!
