Inflation, Cost of living and Consumer Price index are already so amnipulated as to be meaningless in terms of their original intents. Now a new 'phantom number' is proposed. Wouldn't it be more 'transparent' to just keep the numbers accurate? "Low inflation"???? Stable Cost of Living???? Has anybody been to the supermarket lately?

chained is the technical term used by economist to mean that an index number is corrected for inflation. you only use chained data when comparing index values from different years.
another measure that is often expressed in chained terms is the gross domestic product GDP. the GDP is computed in value of dollars at the time. if you really want to know how much the economy has grown (or not) over the years is to look at chained GDP. if you want to compare the current ratio of spending to GDP for example, then you would not used chained data, but use both in current dollars.
so there is a need for both measures, chained and not.
The whole point of moving to a chained CPI is to be more accurate. All the methodology is published and the data is certainly not manipulated (by whom and how?)
