No, you're re-indexing it again. Inflation is accounted for already. You are re-accounting for it.

no, my friend, that would mean that the us per capita gnp was less than 21 grand in 1980. That's not very likely.

Also there is only a 1.7 times growth in 22 years. That's not very likely. One would expect about a 1.8 every ten years with an average 6% inflation rate.

We can probably look up the inflation rates for those 22 years and get an average, but we still have to put it over all 264 months. Even if we use just 3%, we still get a double.
