[AusRace] Jockey Rating Thoughts

[Peter Dean]

Hi,

I am using a set of jockey ratings that have been calculated over a 12 mnth history.
Naturally there are potentially some inaccuracies with jockeys currently out of form or others recently improved and not commanding a high rating.
My question is has anyone ever done any analysis to determine the optimum period over which to calculate the rating and how often to update it ?

Thanks in advance.

Peter
