Chrome Prince, I work using Relative Frequency. I originally programmed the thing in a spreadsheet using macros but have now moved to a home written C++ prog.

Data is 5 start data from Cyberhorse at a cost of $240 p.a. which I parse into a .dbf format for ease of use.

The lookup tables are taken from Thoroughbred Handicapping Tables and some other snippets from Roger Biggs books, the method is described in Handicapping By Numbers but Biggs is one of those writers who won’t tell you exactly how he does it but he does give what elements he uses in A Handicapping Miscellany.

For the past year I’ve been able to match (and sometimes better) his results (he sells his ratings) so I know I’m on the right track and the contents of my purse confirms it.

If it’s consistency yr looking for then this method will provide it and also tell you which races to stay away from (a very handy clue).

The systemateers will find a beaut system in Adventures In Handicapping which shifts the fav SR over 50%.

Incidentally, Biggs books are an easy read but if yr going to use his methods then you need to be able to do some programming (at spreadsheet macro level) or be prepared to cherry-pick your races and be a whiz with a calculator.

As you’ll gather I’m a bit of a fan of his :smile:

Poor Ole Phil ..... just couldn't resist it, could you.

Gotta go, the mainframe is caaaalllllliinnnggggggg.

Felicity.
