thank you so much for your kind words and feedback!
i have no clue where i got unarmored/leather/chain/plate from in the missile fire table–where does chain in particular come from?! will fix in the next version XD i agree that the original scheme is much more interesting and flexible!
there are indeed many things missing from appendix A, since it was conceived of as an abridgement rather than a straight clone. formations in particular i removed from the ruleset since, functionally, i thought they were better abstracted by having however many figures in an (implicit) 3” diameter area. still, i’d be happy to add those rules to be a more faithful representation of the original!
