10K(!)? Well, you do say "hypothetical" 10K. If this is for a class

I was referring to a hypothetical 10,000 dollar investment, not to a 10k
filing with the Securities and Exchange Commission. Sorry for the confusing
shorthand.

I am digesting your earlier lengthy response, which is appreciated. I have
replicated in Excel and agree with nearly all of it and will post my
