Basically it's the real monetary numbers for the US (adjusted to counter the political driven skew which has been increasing for the last 20 years or so). For example, the CPI calculated assuming you bought the same quality goods over the entire period (instead of the current calculation, which assumes you buy cheaper stuff when you have less money, making the official CPI pretty worthless for measuring actual inflation).

It's beyond my understanding of economics and data manipulation to estimate if the fake (official) CPI will ever "catch up" to the actual CPI, and thus reflect actual inflation, but I'm guessing not. Anyway, it's always good to know the real numbers, knowledge = power and whatnot...
