It is critical to know at what prestige level your Pokémon will be kicked-out of a gym so that you could launch a counter-offensive to increase prestige. How do you calculate this number?
For sure, adding an extra guy requires 10,000 prestige. But by that math, my gym should have been 90,000 prestige.
For example, I was in a
level 9, (43202 / 50000) prestige gym and 3rd from the bottom. At what prestige level did my guy get dropped?
