trainertower.com's damage calculator correctly predicts wins. I'll take that as gospel that it works the same. Some notes for those returning players in the same boat as I. Gym leaders have 0 EV but 31 IV on stats. The spread of IV stats seem to be seeded differently in PokeMMO. ie, it may be harder or easier to catch pokemon with the IVs you want.

That is to say this way: https://bulbapedia.bulbagarden.net/wiki/Damage Thanks!
