Read an interesting article recently on course similarity using course data such as incline to finish, tightness of bends etc. A clustering algorithm was used to group like courses together so for example with NH racing Aintree and Kempton were deemed similar and hence should in theory mean that horse who win at Kempton can be followed at Aintree and vice versa.

I decided to take a different route and see if the horses themselves can tell us which courses are good or bad for switching to. The method I employed was quite simple. Take a look at all NH chase races from 2009 to date and as this data is reviewed log winners by track after first checking if each horse running in a handicap chase has won a race before and for each race won increment by the appropriate amount the actual wins and expected wins for the key combination of track_won_at#track_running_at

This will give us a set of AE values for each track combination. Lets take an example, say Jackthejumper has won at Ayr, Catterick and Newbury and he is next running at Perth. The expected wins and actual wins for Ayr#Perth Catterick#Perth and Newbury#Perth will be updated. If he won at Perth then 1 will be added to each of the three actual wins and for the expected wins 1 / BFSP will be added to each of the three expected win keys.

I then printed off all AE values where the expected wins was greater than 5 just to weed out the very small samples. Here is a list of the results in order of AE value. The larger AE values towards the top are the more similar courses (in theory). What might be useful is to check which courseA#courseB with a good AE value also has a good courseB#courseA AE. I leave that for the reader.
