Water and content are coupled: a content figure on a dry basis and a water figure as-is cannot be added without converting one of them. The record states the basis for both.
kf_titrand
Karl Fischer coulometry. Water content is the most ignored number on any certificate.

Section 3
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.
Water at 4.98 % is the largest non-peptide slot on most records and the one most often missing. Where it is present the balance can be closed; where it is not, nothing can.
Where water is high and content was not measured, the recovered mass cannot be computed at all. Water alone bounds it from above and that bound is the only thing available.
11.01 % water on NAD+, above the class specification. Water is the number that moves recovered mass per vial, and it is the one most often absent from a certificate entirely. Here it was measured, which is the reason anything can be said about it.
Water at 4.70 % is the largest non-peptide slot on most records and the one most often missing. Where it is present the balance can be closed; where it is not, nothing can.
10.94 % water on NAD+, above the class specification. Water is the number that moves recovered mass per vial, and it is the one most often absent from a certificate entirely. Here it was measured, which is the reason anything can be said about it.
Water at 4.00 % is the largest non-peptide slot on most records and the one most often missing. Where it is present the balance can be closed; where it is not, nothing can.
Nothing outstanding on this record. Balance closed, recovery computed, purity and identity both determined.
Purity at 99.29 % and recovery at 89.8 % are independent findings. High purity and low recovery is a formulation and fill result, not a synthesis one.
Water at 9.00 % is part of this. Remove it and the recovered figure moves by roughly the same amount, which is why water and content have to be read as a pair.
Water at 2.00 % is the largest non-peptide slot on most records and the one most often missing. Where it is present the balance can be closed; where it is not, nothing can.
Water at 8.08 % is the largest non-peptide slot on most records and the one most often missing. Where it is present the balance can be closed; where it is not, nothing can.
