Turf Talk originally launched in the UK in 1994 as a ratings programme company. The algorithm was developed originally for the Australian market but after seeing the results was soon converted to work in the UK.
It’s success was always largely at the big meetings and in handicaps in particular. It was so accurate with the ratings that it produced that it was even endorsed by Martin Ppe and Peter Scudamore at the time.
It was originally a handheld device called Computerace but has been developed over the years and hasn’t been on sale since but used for personal gains and also some free tips on this website now and then.
