The lowest PPP is no surety of being the opening fav. In a lot of cases this is far from truth. The opening fav is no guarantee of the starting fav. It is also very difficult to monitor as it is four dimensional involving all runners. So you are going to have to sort the horses most likely to succeed away from the field mostly likely to fail. Then you have to lock in your price before it shortens too much. Joe Public is a far better judge of a winner than credit is given. The more strength Joe Public puts on a horse the greater the SR. Down to 80% at $1.20 and 100% on BC.
