I have looked at your idea at least four times and I think you need to work it out so it's a bit more reader friendly. I'm not being mean here. Do the graphics over and over until they are right. If you have abandoned the idea then it does not deserve comment from me. I will continue to look at it the way it is but so far I can't really give you any kind of intelligent comment. Again, I hope you don't take this in a negative way.
