So been thinking about actual hps ratings and how they are different from overhealing stats people get on eso logs. Then occurs to me, that these are healers with best timing of heals. They truly give heals when it's needed. It's a standard metric for reaction time for healers. These are healers who will get you when you most needed in best amount of time.
So I set up to improve it a little more and though picking best results this was best hps score I gotten, but no different from raw healing aka over healing numbers.
