Lots of Objective Subjectivity required here
Joe is bang on.
I would apply this kind of broad thinking:
1. The Dutch were experienced in war with the French. Intermittent for 20 years or so. Therefore military they were seasoned and organized.
2. Individual unit capabilities of such a large army would be unknown unless something extremely notable occurred and was recorded. Therefore a mixture of Elite/Drilled/Raw in approximate proportions 20/60/20 might be reasonable if the Gard te Voet are not present.
3. GtV must be classed as Guard as the gradings are ALL relative.
The Dutch are solid, professional, experienced.. this must be reflected. I would treat the French and Danes the same.
The English were gaining experience in Ireland then Flanders. Noted by the the Dutch as scruffy but aggressive and bold in combat.. learning their craft.
