Did Betty Crocker cake mix, 2023 cut to 13.25 oz shrink?

Source and evidence

Against official inflation: BLS CPI-U (US) “other food at home” changed +4.2% (12 months to Sep 2023, a broad match for this category). The size cut alone raises the price per ounce by +15.1% if the shelf price stayed the same (the source recorded no prices). Every case is compared the same way in the ShrinkRadar Index.

What the source says

“Betty Crocker Cake Mixes Remember when Betty Crocker cake mixes always used to be 18.25 ounces years ago? Some time ago, the mix was downsized to 15.25 oz. and recently shrunk again to just 13.25 oz. — a full five ounces less than the original. The boxes are identical in size. You still add the same ingredients.”
