Rule 1: Eliminate jumps races, races of >=1600 metres and any runners with 10 or more runners.
Rule 2: Consider the top-weighted runner(s) provided it is ridden by a claiming apprentice.

Hope you don't mind a bit of constructive criticism.

These systems might well be okay, but nobody's really going to take them all that seriously if you don't give some results. It doesn't necessarily have to be results obtained over a long period of time, but you should at least give examples of how they've gone in the last week or two. Otherwise it just looks like you've made these systems up in a couple of seconds without any idea of whether they can work or not.

I concur..... otherwise your wasting everybody's time!
