I replied to your other comment about Shadowstats, but will basically repeat the post:

They simply take the official BLS and add a constant. They say so themselves:

> Responding to prior criticisms made by economist James Hamilton, John Williams explained in a private phone call that Shadowstats does not actually recalculate BLS data, rather, the Shadowstats CPI merely adds a constant to the officially reported numbers.[25]

The number at that site will always be higher than the BLS number because the people who run that site simply think it should be higher so they make it higher in an arbitrary fashion. They publish no methodology to recreate their number or say why the x they add was chosen.

If you look at the graph their number and the official BLS number is always different by the exact same amount. And has been for years.

Whereas if you want to examine what BLS is doing you can download code:
