Thanks for the reply but Im still not sure. Are you saying for example that the last three runs should say ie: 78,78,78 and course and distance should say 78,78 or have I misunderstood you? Sorry about this but Im fairly new to this kind of approach.
There are others to consider just not the top 3 in the master, I can see where you are coming from, and I would be interested in your SR for the previous data you have.
The angle of achieving the master figure in the last 3 races and combining with the cse and dis if both match then this a decent bet on the AW, no matter where on the ratings the selection maybe.
