I've a neural based system/s and looking at using ratings to help with selections...so have a couple quick questions on ratings.

Unitab ratings - What are they based on? I think I remember wesmip mentioned unitab rating are based on speed. Is this correct?

Who provides the form rating for tabracing.com.au/ I know it says Sky form, is this the same as Techform?

Are techform ratings available free and has anyone have any comments regarding them i.e. long term S/R, find them accurate? etc

...or any other free ratings, who would you recommend.

Thanks in advance!
