If you are a real systems buff there is a service call ************** GTS by Marcel Plant & accociates.

For $1000 you get back data of 20,000 races .
With this you can start testing any criteria & most systems criteria that one may want to check , to see if it`s got legs or not .
It has a provision to greate & save your own system criteria ,if you subscibe to their daily form data service , you can have your system scan the entire days various meetings to find your systems selections within seconds.
It will show ,profit & loss , strike rate , etc.within seconds, it can do more in one hour than someone could do in a month.

For another $3000 a year they supply a daily form service plus update past results to add to you data .
If one makes money out of any system idea ,then I guess its not expensive , no matter what system you come across they all have winning $ loosing months.
You have to be mentally prepaired for that .
