Thank you so much.About the oil formula. I do not know much about the intricacies of mechanics. But judging by the wiki ( https://wiki.guildwars2.com/wiki/Gain_X_Based_on_Y ), thenConversions are based on stats from the following sources:Attributes gained naturally from levelAll gear (stats on armor, weapons, trinkets, etc)Rune flat stat bonuses (all runes)Trait bonuses that give statsStacking SigilsFlat bonuses from FoodFlat bonuses from Utility Therefore, I figured that should be included in the formula. The fact that Behe does not heal himself, I know, first of all I wanted to evaluate healing to allies, but I completely forgot that I also need healing. And this also affects the overall performance, as you have shown.
