Hi thevig,
the reason i mentioned standardising the data is that you can place an accurate score against every start a horse has, then using the Mean & Standard deviation of each horses score you can then develop an Oddsline.
so to find the z score of a two horse race, you would do the following. zscore=HorseA (mean score)-(minus) HorseB(mean score)/(divided by Horse B(standard deviation) you then look up the zscore on any zscore table on the internet this is the probability that horse B would beat horse A , if horse A ran an average race.
you then reverse the Mean scores and use Horse A standard deviation to find the probability of Horse A beating horse B if horse B ran an average race.
