There are Trainers For Courses and perhaps there are Tipsters For Trainers.
One area for developing a system could be to study If Newspaper Tipsters perform better with certain trainers. The reasons may be that they have more knowledge about certain trainers than others or they have inside information from the stable.
The Tipster Analysis on the Racing Post Site is ideal for research for such sytems.
The Following Google Doc link is just an example of how a sytem could be developed.
