Are my mitigation numbers off ?

It is, so you'd need to include that in the calculation as well (since the interplay between block rate and parry rate is complicated). So effectively, a parry rate of 25% would only affect those physical hits that couldn't be blocked, so (100-{blockRate})% * {parryRate}%. Assuming 25% for both, that's 25% of 75%, or 18.25% (times .2 is only 3.65% mitigation, versus the 5% it would have been otherwise).

Correct me if I'm wrong, but doesn't Awareness also skew this number? Using it typically increases the efficiency of Bulwark because Crits can't normally be blocked or parry'd... Though I'm not sure how the heck you'd work that into the math...
