Now that we are near the end of the challenge I reckon it's time to declare how we actually arrive at our ratings.
I use :
1) My speed ratings (Beyer based)
2) A set of ratings based on sectional times - I only do these on Melbourne races
3)A commercially available set of ratings - usually Price Predictor.
My final selections are based on a consensus of the 3 sets of ratings.
I guess it's not surprising but I've found that over the last three years the consensus has out-performed any of the individual sets of ratings.
