I honestly have no idea what you are talking about. I'm not saying anything other than that's where the numbers comes from, and it's a lot more complex than one simple number if you poke at it at all. The fact that overall it's at 7%, with things like furniture being below 1%, doesn't change the fact that food is over 10% with specific items being more. Similarly housing overall increase was in the 5% range, but because it's such a large portion that is a massive increase, even if it's below the overall CPI.
If anyone wants to use CPI, fill their boots, but it doesn't represent the impacts on individuals, because that's not what it's for at all. No one is fiddling with the numbers; the numbers simply aren't being used for its intended purpose by people who understand what it means.
But realistically if a rise in anything costs me an extra hundred bucks a month, I'll care a lot more about that than an increase of a few bucks a month, regardless of what that works out for a percentage. That's why mortgage rate hikes can be devastating, a small change can result in real large increases in real terms (vice huge percentage changes to low dollar value items that have low real term impacts). Similarly the cost of gas nearly doubling in the spring could add hundreds to commuting cost every month, and lots of people don't have the option of public transport for work.
For some folks the cost of bread might be the critical one, for others it will be something else; all I'm saying is CPI is a 50,000' general indicator, the general impact on individuals is much more complicated. When I plugged in my personal inflation to the tool I was around CPI overall, but if I was to start commuting back to work daily it would go up to around 12%, so really depends considerably on your personal specifics, and can change very quickly.
I do maintain though that calling it 'Justinflation' is fundamentally ignorant though, and completely ignoring the real causes of global inflation that we really can't do anything about.
