I think you bring up some interesting points here, and my experience and
observations largely lend credence to what you are saying. I'd like to know
however, just for my own personal knowledge, are the numbers you are using
above based on some broad analysis or study of multiple providers, or are
you deriving these numbers likewise you're your own personal observations?
