Kedaman,

I think you just picked up on this nifty little formula which may or may not be right, and now you're trying to make it seem you understand it which you clearly don't, and you should've kept your mouth shut in the first place.

I was wondering how you found out about it on the way home.... was it inside a bubblegum wrapper, or did someone leave a Reader's Digest on the bus....

But anyway what you should do, assuming you have one, is cite a reference - and not just a url, but preferably something subject to some peer review process, then we can assess it for ourselves.
