I will be diving with Aldora for the first time at the end of May. I did not know they all come up together. Not my preferred method. Not only due to different SAC rates for different divers but also because not all computers are created equal. I have a Suunto Cobra and it is pretty conservative, I would not want to cut another diver with a more liberal computer dives short.

Keep in mind that many if not most dive sites in Cozumel can be dived more conservatively individually while diving with a group to extend your NDL by just managing your depth compared to other divers in your group.
After all, dives aren't done with all divers holding hands staying tightly together, it's very typical on many dives especially wall types for the divers to be spread over possibly 20-40 ft of depth differences between buddy pairs. It's typical to have divers deeper than you and shallower than you on dives as different divers are investigating different levels of the wall or reef structure during the dive.
You can easily stay shallower when you want to or need to during the dive to 'bank' or extend your NDL. (this is the beauty of diving with a computer and getting credit for it being a multi-level dive) I'd consider this just routine NDL management that you would do automatically at your level of experience and nothing will change just due to the way Aldora dives.
