Are Maple and Graham in the same 'divison'? (ie. 4a, 5a, 6a)

If so, it looks like it will be very hard for Mr. Graham to earn his fourth title if they are both in the same bracket at the state tourney this year. However, he (Graham) does seem to peak when he needs to. Should be interesting (ala Cornejo vs. Zuzsa).

Sorry the for mispelled names.
