Hi Coffee
The program I use is the most sophisticated program in the world, it is called TRB GTSi.
(The Ratings Bureau)
It can do a lot more than Price prdictor but it is also 4 times the price.
It has its own data base which can be loaded daily which includes the scratchings.
They send out a disc at the end of each month to update your data base.
It has a pre-post market as per newspapers.
You can anylise say race number 1&2 only.
You can isolate months of the year or days of the week or Country,Povincial,Metro or class of race or any of its last 10 starts.

It`s amazing .
I have created & bet on over 100 systems 7 days a week.
It can run all 100 at once & takes about 2 seconds to work out the lot,now thats amazing.
It would normally take 9 hours to do that manually.
It is very flexable.
You can isolate factors first before you include it as an actual rule.
