Blast ignoring PDRate?

The MinNoCritACBDmg he dealt was 81616.
what I have found is 81523.
With the damn buff the damage rate is 99284~105161

From my calculation:
Dual charge formula is not changed after BB , 130% * 1.5 + 12.5% * 1
So: ((11042 ~ 11747) * (130% * 1.5 + 12.5% * 1) - 850 * (0.5~0.6) )* 480% * 0.9 = 96777 ~ 103464
a bit less?
IGNORE PADamage... and just see what's happening.
(11042 ~ 11747) * (130% * 1.5 + 12.5% * 1) * 480% * 0.9 = 98980 ~ 105300
perfect fits the number.

But when I use the formula on Blast it doesn't work well.
(11042 ~ 11747) * (130% * 1.5 + 12.5% * 1) * 226% * [1 - 10%*(1-7%)]
or
(11042 ~ 11747) * (130% * 1.5 + 12.5% * 1) * 226% * [1 - (10% - 7%)]
