How do berries and diminishing returns work in gyms?
When I heal something in a gym, it gradually heals less and less until I'm getting numbers like pic related.
But yesterday I stood and fought a gym, 1 Snorlax, that kept getting healed to max over and over. Took about 15 battles until he stopped getting healed back to full.
Does it only lower your heal based on an individual on an individual Pokemon?
