Well we didn't win but we survive to invest further:
MR No2 Smart Maxie 2nd $1.9plNSW
POT = 6 units invested and 9.5 units returned = 9.5/6.0 x 100 = 15.83%
the point here is that although backing a loser(2nd) we have profited and have funds to invest on future races.
The benefit of a relatively conservative approach to your wagering is obvious.

Cheers.
