“Estimates of the number of days per year from 850 Ma and 360 Ma of 435 and 397 respectively all compute to an approximately 3.5 × 1012 W average continuous loss of rotational kinetic energy (see Wells 1963; Munk 1966; Vanyo & Awramik 1985).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
