You can't limit the AP by yourself. Only if both contenders agree upon an AP limit this would be valid.
from post 7
The challenges will be done in max AP, but if both participants agree to use lower AP it is up to them. I for instance will handle them as CG challenges and thus use full AP.
If you don't have full AP and can't or are not willing to rent them then the title will pass on to knightwalkerII.
I will try for level 12 after Baweja and agent004 figured out who's the golden duck :)!
