I know how to assign personal armor BAR values based off of what armor my character has on when using hit location rules, but not without hit location rules.
I know that, "Basic combat rules presume that all characters aim their attacks at the target's center of mass, and so any damage done is generalized," (from, page 190); How do I--mathematically--generalize all of the various BAR values of all the various pieces of personal armor that a character has on?
Moreover, "When using hit locations, the BAR of any personal armor must be that of the armor in the specific body location struck, rather than the character's overall BAR," (from, page 190.) So, mathematically, what is a character's overall BAR?
