You concede that monthly inflation is volatile but then proceed to assume it is has grown uniformly and speculate that it will continue to grow uniformly? Umm...

The point is that the annual number is often rather confusing from a reporting perspective.

And that an annual number is diluted and will only feed in slowly over time.

If we knew inflation was permanently at 5% from now on, a blend with 2% for 11 months and 5% for 1 month, is not informative.

They said: "12*0.4% is 4.8%. Inflation is running at an annualised 4.8%."

This is patently wrong.

Because it's 1.04^12?

Or are you addressing some other flaw?
