Maybe I'm blanking, but I don't remember ever suggesting anything you describe. Maybe you are confusing me with someone else?
From what I understand your calculations are driven mostly by the desire to adjust for something or make something to work better, but it's not clear at all to me what it is that you are trying to optimize and why do you choose that particular way to fix it. The final result makes very little sense to me. Maybe we should have another chat (or even voice) session tomorrow?
