What is the smallest XP amount you earned in a match?

CPU vs. CPU dosen’t count.
Online - 82 (back when Cinder came out.)
Single Player: 13 (9 x 1.50) champion level survival.

2 xp. In an online exhibition vs a buddy to show him Rash’s time out losing animation. One light punch and a time out will give you 2 xp (and that may even be after multipliers)
