I don't use systems because the thing I don;t understand about systems (most anyway) is that for example the one below; those are many of the factors i look at anyway when doing the form, except apart from the rigid structure of the guidelines I look at quality of last run, luck etc. I am a bit baffled as to why you would want such rigidity? I am not having a go at it or anything I would just like some input.

Cheers
