These systems are freely available around the Internet (some idiots charge you for them on Ebay!), and have NOT been tested by Win2Win Racing. More than likely they will not show a profit as is, but adjusting or adding a variable may make them profitable long term. They can also help direct you towards selections that are worth a second glance. Always paper trade any system first, on the forum if you wish, then everyone can throw in their thoughts.

DOUBLE TOPS
Here is quite an old yet remarkably effective system that shows a level stakes profit most months. Prices vary from odds-on to 4/1 and the longest losing run since April 2001 has been just 6 on one occassion.
Paper: Racing Post
Examine the 'selection box' of tipsters for each in the Racing Post. For a selection to qualify it must be tipped by the first four tipsters in the 'selection box'. That is, it must be the selection of Postmark, Postdata, Topspeed and Spotlight.
No bet in handicap races, nurseries, claimers, sellers, amateur or apprentice races.
