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.

Two decimal places on 99.52 % implies repeatability better than 0.01 pp, which no laboratory here claims. The number is sound; the printed precision is more than the method carries.
Index data team

Two decimal places are retained because the source reports carry them and truncating would discard information where a laboratory genuinely reports it. The uncertainty budget on /methods/uncertainty-budget/ is the right thing to read alongside any purity figure on this site.

Two decimal places on 99.93 % implies repeatability better than 0.01 pp, which no laboratory here claims. The number is sound; the printed precision is more than the method carries.

99.68 % is normalised area, so it is silent on how much peptide is in the vial. Content and water are the numbers that answer that, and both are on this record. Purity is the good news; content is the actionable news.

A figure reported to the nearest half point is reporting less precision than the method has, which is the opposite of the usual complaint. It is conservative rather than optimistic.
AX-2026-043477
Declared figure and measured figure on this lot agree within measurement repeatability. Whatever the rounding convention is doing, it is not moving the number away from the material.

Two decimal places on 99.37 % implies repeatability better than 0.01 pp, which no laboratory here claims. The number is sound; the printed precision is more than the method carries.

Precision and accuracy are separate properties. A figure rounded to a half point can be more accurate than one printed to two decimals, and on this lot it is within a tenth of the independent median.
