I would keep the speed, quickness, game speed, and player speed at the same values as User vs. CPU for Offline Association.
At 45 Speed/Quickness, the CPU goes at the same speed as the User does with a setting of 50. So in a CPU vs. CPU game, the values stay the same so that the animations and flow of the game remains the same as a User vs. CPU game.
Glad you're enjoying the set!
No problem!
And sorry, but this is my first year of doing my own official slider set, so I did not have a set for 2k11.
