One proposal the Office of Management and Budget suggested in the filing is to shift to so-called chained CPI, which regularly shows a slower pace of price gains than traditional measures. Chained CPI shows slower inflation growth because it assumes consumers will substitute less expensive items when prices for specific individual goods increase significantly.

That is why I like Shadowstats,  for the most part they use fixed variables.

Best regards,

 There's no numbers in the article to go over.

 If there was some algorithms presented we could run parallel the method Shadowstat claims, and the revised ones discussed and see if we get the same numbers.
