What we probably need, should we desire to know how it works rather than rely on our anecdotal evidence, is for us or somebody else to mod in some degenerate shield with an absurd defense value to lower base defense or set it to some convenient total number when considering the attacker for the test and a grotesque high parry value and run a series of structured tests. I won't have time to do this today, but later this week should be an option.
