This video demonstrates that when the BB Priest hits party members with the Holy Radiance spell it adds those hits to the hits in the character personal record. This also happens for any other auras, buffs etc.

This gives inaccurate data, and could probably be solved by not adding any non-damaging hits to the personal record.

On second thoughts, that check would not work as it wouldn't include debuff hits. A better way of doing it would be something like checking if a hit is non-damaging to a party member instead.
