1 roll in a 2 roll tank

When developing one roll of film in my two roll tank I tend to get varying results. Usually over developed or right on. Is this because of the extra room in the tank and the chemicals can move more vigorously? I don't like to wait too long to develop rolls, but maybe this is my best bet? I usually use TMax 100 in TMax developer at 68' for 7 min. and agitate 5 times every 30 sec. and get very good results (with 2 rolls). Maybe shorten the developing time? Janet
