But in the current world, getting 160 off a gem is similar in survival granted, becuase your base resil RATING is SO LOW now, instead being bolstered by the base reduction.
PvP Power is a harder model, but generally the gems are weak. That being said, I think you should figure out expected damage to calculate cases that are hard: EG, socket bonus is PvP Power, kind of thing.
