I think your calculation on mitigation percentage when bb/sbb stack with ubb effect are wrong.

In japan actually, the calculation for damage mitigated is:

UBB effect :100% - (100% x 0.75) = 25%

then BB/SBB : 25% - (25% x 0.5) = 12.5%

So actually when mitigate effect from UBB stack with BB/SBB, the damage taken by units will be 12.5%, not 1, because the calculation is step by step, not adding it straightly.
