Hi all,
I have been producing all weather speed ratings for 15 years, using Mordin's method fronm his book. I have an excel spreadsheet which automates the data crunching process. I can get through a whole week's winter fixtures in about 2 hours.
I am happy to share this spreadsheet for free if anyone is interested.
n,b I get actual racetime etc data from raceform interactive, but this can be gathered manually from a number of different sites, racing post, ATR, timeform etc
