Regarding "The first time you go into Quest Mode each day, you will roll the XAI. The roll of this XAI will affect how much experience you gain from each Digimon that day, as well as how difficult the fights will be." For a while I was logging the experience for my quest battles. It seems each opponent has 2 possible experience values. 4-6 dots gives the lower amount, and 1-3 or 7 dots gives the higher amount. I would guess that 1-3 dots is high difficulty high experience, 4-6 dots is low difficulty low experience, and 7 dots is low difficulty high experience (best of both worlds).
