Area percent assumes unit response factors across every species present. At 99.93 % the assumption barely matters — there is not enough impurity for a response-factor error to move the figure by a tenth.

Section 2
Annotations
Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it. Where a handle has made the same point on several records, one instance is shown and the rest are reachable from the records themselves.

Area percent assumes unit response factors across every species present. At 99.46 % the assumption barely matters — there is not enough impurity for a response-factor error to move the figure by a tenth.
Nothing adverse on this record. Purity 99.60 %, largest single impurity [D-Thr]-diastereomer at 0.21 %, and a mass balance that closes. It is a clean record and the index has no note to add to it.
Area percent with assumed unit response factors gets less reliable as impurity content rises. At 3.29 % total impurities the response-factor assumption is worth about a tenth of a point, which is small next to the gap but not nothing.

A rounded purity and an unrounded impurity total on the same certificate will not sum to 100 exactly, and that is a rounding artefact rather than the arithmetic failure rule AX-R02 looks for. The slack allowance exists for it.
