This thread is like an Abbott and Costello skit.
Define the paramenters you want tested.
1. Best race last time out.
2. Best of last 2.
3. Best of last 3.
4. Average best 2 of last 3.
5. Most representative race of last 3.
6. Best race of last 3 eliminating off tracks
Make up a list like that and then you might get feedback on how a certain set of figures does in that category. You can't just ask for a return without specificying the criteria.
