Trivia

 * The highest possible amount of EXP possible to be gained in catching Pokémon is, when Trainer catches it for the first time with excellent, curveball, first throw, and with bonuses such as: first catch of the day, seventh day in a row, expert handler, and using Lucky Egg while there's an event with triple XP. Which results in 20,160 EXP in total.
