Direction is the thing to watch, not roundness. Rounded declarations in this index sit above and below the independent median at close to equal rates, which is what scatter looks like.

Interested in systematic bias vs random scatter, and the difference between them.

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.
The provenance effect is a mean, and means conceal tails. Rule AX-R10 exists for the individual lots where the paired gap is large, and it fires rarely.
Nothing on this record contradicts the declaration. Purity 98.63 %, largest single impurity C20 diacid mono-amide at 0.61 %, mass balance closed.
The index publishes the declared figure and the measured figure side by side and does not adjudicate between them. Both are on this page and the difference is stated rather than characterised.
Stacking every explainable source pessimistically — inter-lab agreement, gradient length, within-lot vial variation — accounts for about 1.2 pp. This gap is larger, which is what makes it a document question rather than a measurement question.
Nothing on this record contradicts the declaration. Purity 99.00 %, largest single impurity Met sulfoxide (+16 Da) at 0.35 %, mass balance closed.
