If you max this treasure to +9 (400% bonus), you are getting the maximum possible XP.

In this game, we cannot earn more than 5 times of the base XP at any situation.

For example, if you run for 1 min and you earn 600 base XP, the game doesn't care what combination do you use in treasure slots, pet and cookie. You earn 3000 XP max in this case.
