Hermes,

I liked your system. I think you are being a little harsh on yourself. The problem with qualitative systems is they require human input and believe it or not, we make mistakes fairly often. (I made a costly one in the Doomben 10,000 recently!)

Stick with it, the rules are fine and you can only learn their application through experience. Eventually you will can a rule or two (you need to) but which ones will only be learnt through trial and error.

Good luck
