Experience gains in this game make no sense. At all. Either that or I'm missing something.
Here I caught a level 45 Magmar. Combo bonus, size bonus, and an excellent throw. 1,426 XP. Cool.
A few minutes later, I land a great throw, and get the combo and size bonus. Except now I'm getting double the XP despite making a worse throw with everything else staying the same.
And then I break the combo, so I don't get the combo bonus, but catch one on my first throw. Get it on a great throw and a size bonus. Suddenly I get a massive 9.0 multiplier.
None of this makes any sense and it all seems entirely random.
