I am still working on a force a play test game so most of the questions about how it all works rather depends on what happens when I have tried out the rules I have proposed and seen if they produce results that match the original accounts though finding battle accounts at this sort of level of detail - Granularity as it has been referred to is a bit of a challenge.
I am not sure about tests as such as Sharp Practice Lacks them using shock accumulation as its Morale mechanism but I have thought about the mechanisms described in TSS for determining if cavalry charge home as a basis. I however want to run some play tests first.
Thank you for your feed back it helps me to shape my ramblings into something coherent or as close to it as I get.
I am inclined to agree with the comment below that infantry against infantry fights tended to become prolonged musketry duels. Duels which where often rather indecisive of all armies of this period only the Swedes in the great northern war bucked this tendency and settled things in hand to hand combat.
