If inflation was still calculated the way that it was back in 1980, the official rate of USD inflation would be above 15 percent right now (as per Shadowstats.com)

Shadowstats is funny. They don't actually calculate inflation.

They have graphs showing CPIs to the 1990 and 1980 methods here

CPI is Price Inflation, but of course there is also monetary inflation - or 'classical' inflation. Don't know if shadowstats tracks that.
