As for the knights, I think I would leave them as is, believing that the DOK Knight class represents Charles' household knights, who were of high quality. Essentially, a Burgundian Ordonnance army should follow the pattern found in the lance, which was the basic administrative grouping in the army. The pikes were generally overrepresented, so it would not be unreasonable to up the one pike to two. This will produce a small army, not unlike its historical prototype. Handguns may either be crossbows or bows.
Artillery are the same as crossbows.
Burgundian gendarmes often fought afoot. Again, the percentages listed represent the percentage of available points that can be spent on each troop type, not the percentage of that troop type in the army.
