I'm just a lay person and he's been analyzing inks for years so I'm happy to give his opinions an appropriate level of deference, but I'd still like to understand why some of his statements about what is odd in the ink seem to be at variance with what I'm finding elsewhere including in the published literature.

Following up with an example from the scientific literature (You are not allowed to view links. Register or Login to view.): 

XRF analyses of iron gall ink

Multiple studies of iron gall inks have demonstrated that XRF analyses can be used to distinguish different hands or manuscripts according to the ink compositions [You are not allowed to view links.

This is mostly based on variations in the copper and zinc contents relative to iron, but other elements, such as manganese, potassium, aluminium, sulphur, silicon and lead may also be distinctive markers of separate inks. An ambition to not only identify components in iron gall ink, but to also quantify them with the help of XRF analysis, has played a part in several studies. In an investigation of a 14th century breviary, Aceto et al. used standardless quantification through a freeware software provided by the International Atomic Energy Agency, IAEA [You are not allowed to view links.
