That is, if I can catch a Pokemon with a CP of 1850, but then I checked the IV and perfection, and its perfection can be any where from 55% to 76%.
Now, if I have another Pokemon with a perfection level of 97.8%, and I spent time powering it up, but so far its CP is only 1850, the same as the other Pokemon.
Now, these two Pokemons have the same CP but different IV and perfection. If I let them stay at a gym, do they have the same amount of chance of winning in general due to the same CP, or is it hard to say?
In some situation, if I catch a Pokemon with CP of 1950 but perfection of only 60%, then I wonder if I should let it stay at the gym or let my Pokemon with CP 1850 and perfection 97.8% stay at the gym.
