Well, I don't want to give away the rules, not just yet anyway, but I can give you some sort of idea.

System A, B and C are ALL based on the 100 raters. I just use different ways of working out the selections. System A is based on 100 raters with certain specific formlines. System B is based on 100 raters which are in good recent form and are well fancied, and System C is a longshot system based on 100 raters that tend to be overlooked and can bob up at good odds (as did Navy Lady).

If the systems continue to perform well, then I may post the rules a little further down the track.
