Shadow stats isn't credible in any way. They can't even be bothered to take the raw data and apply the 'old' weights to them, so they just arbitrarily add a few percentage points to the CPI. The BLS has dedicated far too much effort into showing why they are an asinine source for 'data':
If "real" inflation was 7%/year, in 10 years, the price of everything would be 100% higher than it was previously. How many things in your life are twice as expensive as they were in 2004? Now how many things aren't twice as expensive?
