I have been using Past the Post for about a year: http://www.pastthepost.com.au/ There is about 5 different form guide options.
I use 'fields' to get the basic lists I've shown here and I mainly use 'Time-long form' [last 10 starts and includes adjusted times for distance and other time considerations too] for serious form study. Most horses are rated [dry or wet ratings] and almost all have running position [L, P, M, B]. The site is cheap for the info available so it doesn't have scratchings.

Todays 3 selected runners were 60/1 16/1, 18/1 so they didn't really firm into betting propositions but I did have a small e/w on the 16/1 for zero result. The track was dead 4 too.
