And when I look at the average rate of inflation from 1970 to 2017, it is 4.01% per year: http://www.wolframalpha.com/input/?i=1000+1970+dollars+in+2017 http://www.wolframalpha.com/input/?i=1000+1970+dollars+in+20... Both of them are exponential growths, but with quite different rates.

And for 1970 to 1980 it's 7.82% per year: http://www.wolframalpha.com/input/?i=1000+1970+dollars+in+1980 http://www.wolframalpha.com/input/?i=1000+1970+dollars+in+19... As I said, there was a surge around 1970, so yes, if you take a period that includes that surge, it will probably have a higher rate than one that does not.
