I'd like to see independent (ie. Not made by government agencies) estimates of real world inflation.

Do they exist?

See the Billion Prices Project by MIT for all things inflation. Still lots of government data there though.

Google "Big Mac Index" for an example.

TLDR: inflation doubles prices in 18 years. So it is math.pow(2.0, 1.0/18.0) - 1 = 3.8% per year between 1986 and 2004.

4.15% between 2004 and 2013 and has been rising further. Let's assume it's 4.3% to 4.5% now ...
