Personally I don't think it is possible to get a winning system out of the info on the TAB websites - I have tried it myself in the past. There are several pieces of info that I consider absolutely critical - some of these are available from the TAB if you go looking for the individual form, others are not there at all:

1. Distance beaten in lengths (or winning margin)
2. Distance change from last start
3. Days since last start
4. Some indication of change in class from last start (eg. prizemoney for last race v's prize for this race gives a very rough indication).

Plus a few others - don't want to give away all my secrets :wink:

Personally I think subscribing to the Cyberhorse form has been one of my best moves as all this info is included and you only have to look in one place.
