I have attached the grade avg figures for all Grade Classifications in Victoria.
the idea is to check each formline make a note of the avg grade figure then add the margin beaten.
Then do an avg of the last 6 or 5 starts to get each dogs Class rating.this is a very simplistic method but its generally very effective as with Horse racing you need to balance your Class figures with Speed/Time figures
A very big hint!!
Remember Class shows in the most recent runs, Speed shows in all runs..
