Sith raid damage

I call B to the S. “At the start of his turn Nihilus recovers 3% protection for each buffed enemy”. That image above suggests that 3 of every 4 hits g12 maxed toons inflict hit protection. There is no mathematical way nihilus should be getting that much protection for each turn. At most, it should be 15% (5 buffed enemies x 3%) which would zero out after a single hit. I also am seeing the protection line go well past 50% when nihilus starts his turn. I’m thinking this raid is buggered.
