I don't really know the process of doing the math here (this is actually the chance of Shiny Pokemon, if anyone's curious). Once you've battled 500, a 3% chance of getting 1/512 odds is added on.
So 1/1365 is your chance of getting a Shiny, but each encounter with a Pokemon has a 3% chance of changing the odds to 1/512, which are much higher. I'm curious what my total odds are then, basically.
Normally (I know it doesn't really work this way), I would say that if my odds are 1/1365 and I go over 1365 then I'm "over odds." I'm curious what would be the expected "odds" when you factor in my "3% chance of 1/512."
