Started googling and can't find how shadowstats collects or analyzes their data. What is the difference in the two calculations and why are they important?
They use the same methodology for accounting inflation as was used prior to 1980. Up to that point, rather than measuring "the general price levels," the inflation numbers could reasonably be used to quantify maintaining a standard of living.

The CPI chart on the home page reflects our estimate of inflation for today as if it were calculated the same way it was in 1990. The CPI on the Alternate Data Series tab here reflects the CPI as if it were calculated using the methodologies in place in 1980. In general terms, methodological shifts in government reporting have depressed reported inflation, moving the concept of the CPI away from being a measure of the cost of living needed to maintain a constant standard of living.
If the old methodologies had been in use constantly since 1980, Social Security payments to retirees, which adjust annually (COLA) based on the CPI, would be approximately double what they are today.
