The cause of the increasing 14C background values as a function of declining amounts of infinite age material in the synthesized graphite is very similar amounts of micro-contamination added to all synthesized graphite samples during the combustion/acidification and/or graphitization process.
“The cause of these effects has been demonstrated to be due to the very similar amounts of micro-contamination being added to all synthesized graphite samples during the combustion/acidification and/or graphitization process that we have previously described (Vogel et al. 1987;Kirner et al. 1995;Brown and Southon 1997).”
From Misunderstandings Concerning the Significance of AMS Background 14C Measurements (2018) · cites this paper as Brown and Southon 1997
The inversely proportional dependence of contaminant carbon on sample size has been studied using a simple model that assumed a constant mass of modern carbon (MC).
“This inversely proportional dependence has been studied by using a simple model that assumed a constant mass of modern C (MC) (Brown and Southon 1997).”

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.
