I tried to set up counting method with excel, using 1 dollar bets on the "top 5" in various selection methods ranging from 1st top 5 favourites to 10 or so various selection methods including tipsters.
After initial testing of the process, after 1000 races counted, in a word, No.
There was an obvious pattern emerging , which to take it much further was a waste of effort.
This assumes the tests done were in real time, results taken were at interim.
Therefore a few races missed while waiting for results on the previous "bet race".
