+70The tool assumes complete dissolution, an accurate label mass, an accurately measured diluent volume, and a syringe manufactured to its nominal scale. Each of those is an approximation:
+71
+72* incomplete dissolution leaves a concentration lower than calculated and a suspension of unknown uniformity;
+73* diluent volume drawn on the same syringe used for dosing carries that syringe's own error;
+74* syringe volume tolerance under ISO 7886 is a few percent of nominal capacity, which at the bottom of the barrel is a large fraction of a small dose;{{r|iso7886}}
+75* [[Peptide aggregation|aggregated]] or partly degraded material has a peptide content lower than the certificate reports, and no arithmetic detects that.
