Now since Darren beadman has been riding so well I thought i'd take a look at his stats for this Sydney season beginning August 8 (Saturday Sydney only)
106 rides -27 wins outlay 106 units Return $108.3 units 2.17% profit
-53 places outlay 106 units Return $89.3 units 15.76% loss

Not too bad if you be a little choosy and dont back him every time
cheers
