Re: math averaging
bnelson,
When computing average change you are faced with a dilemma. Do you want to consider the average change to be the amount of change you averaged over some number of years? Or, do you want to know the amount of change that would produce your current year given the year you started?
It's a personal choice in my opinion. Sometimes one is better than the other. Sometimes neither is worth anything.
Take a look at the attached and it may become more clear.
