Turns out the levels are all wrong. I was doing a custom while waiting on some friends to finish their game. She has the 15% at level 1...she gets 25% at level 7... I had to quit the custom game because my friends finished, but it was still 25% at level 11. I'm guessing it's after 6 levels again...so I would guess it goes to the 35% at level 13. That makes the most sense...to go from 1 to 18, you gain 17 levels, so 6 levels is the closest to a third of the way which would mean levels 7 and 13 are where they increase.
