No disrespect intended but,
I don't think that the original poster wanted equations.
He wants actual numbers so that he can run a comparison.
I know alot of people here can quote equations....but few actually use them on their business.
The reason....I believe is that it is time consuming and some might not know how.
I am just starting my business in a few weeks and I would post some of those numbers if I had them. Once I get started I will post some for comparison purposes.
Maybe I can work out a spreadsheet that helps the common man see where his business is going and what it really is producing.
Hmmm...maybe a website that does that for free so that the SCRUBS can see that they are PAYING to WORK. Something to think about.
Just my thoughts.
