Oh, this got even worse than I expected. Let me show you another graph, then. This is FRED's official price index, which is the source of the blue inflation line in that graphic. I've overlayed two red lines for its value in the eleven years from Aug 1972 to Aug 1983, plus two orange lines comparing its value now (Mar 2024) to Mar 2013, also eleven years. Notice how the gap between the red lines is a price rise of $58.2 on a 1982/84 $100 basket, while the gap between the red lines is a rise $79.948, which is significantly higher: https://fred.stlouisfed.org/graph/?graph_id=1327450

Now imagine how much worse this would get if we did these calculations with the yellow line data instead, which is essentially the same in the 70-80s but much worse today. (Or maybe also imagine how much worse the past ten years could be five years from now if we got a second inflationary spike like the 70s-80 did, making this a more apples to apples comparison!)
