"Using Sefia's SBB will bring your overall BC drop rate up to 70%. This means that you are bound to produce at least 70% of each unit's Drop Check."

Doesn't 70% drop rate mean that on AVERAGE you'll produce 70% of each unit's drop check, not at least? Shouldn't you get a skewed left distribution with a mean at 70% of drop check?
