Don't know about M$ Excel, as I don't use it. I use Open Office.

Am I rich? As in lots of money? NO. Mind you, I ain't poor either.
Rich like woofer? Quite possibly.

Why am I betting so small?
1: lots of systems work fine on paper, but go to pot as soon as you put money on it.
2: I'm fairly certain I need at least one more input variable into my equations, as my correlation between my rating scores and actual final placings is still a little too shy of 100% for my liking.
3: Maybe it's a hobby. Exercises the brain cells. Gives me a nice diversion from work. Maybe I'll get rich & give up work....LOL.
