Empress Ignore/boss damage calculations (DB).

I'll always have over 66% ignore.
It does not look like anything below 200% boss can beat 100% ignore, on ANY boss mob.
Not possible for any dual blade.

If i had to guess since you say that boss> PDR

going from 66% to 100% PDR is a 1.5151 increase with a mob of 70 defence MATH: (70 PDR/(70PDR*.66))=1.5151

Going from 2.35 to 2.75 boss is a 1.17 increase. MATH: 2.75/2.35 = 1.17

So even though you are flat increasing bossing by more, looking at the ration change of the two Increase your PDR is more beneficial.

ninja'ed... sorta anyway
