I had a similar experience with my new Suunto Gekko. It was my last dive of the week, and I felt I was pushing the limits of this conservative computer as I began the ascending portion of the dive. At one point it was telling me I should both descend... and ascend to do a deco stop! Anyway, it told me I needed an 8 minute deco stop with a 10' ceiling. I did 6 minutes at 15' and then slowly ascended and got on the boat. I got the Error lockout deco violation from my Gekko. DM told me I wouldn't be allowed to dive for 48 hrs. The Gekko told me not to fly for 48 hours, but that is its default response...not geared to how much of the deco stop I actually did. I had a solid 24 hr block of time b4 my flight, so I figured I would be ok (I was fully aware I was taking a calculated risk). And I am ok, and experienced no bad symptoms.
Just reporting this as a data point really. I love the Gekko, I will not adjust it, or try to get around its algo just to increase my bottom time. I like that it is conservative, and I will plan/execute my future dives (especially the late week dives) to abide by its conservative algo. I have a wife and kid I love and want to see after every dive trip!

Actually, I have seen this, in 2008. A diver on a wall dive made a too-fast ascent from about 90 feet to 60 feet to see something, dropped down the wall again and repeated the quick ascent to 60 or 50 feet.
His Suunto Cobra (the original version) was very upset when he didn't hold a safety stop but instead surfaced (nice and slow this time). The RGBM side of its algorithm had decided the safety stop was now mandatory* because of the micro bubbling he had probably encouraged. At least that was my take after some research.
When he didn't pay attention to the constant beeping after boarding, the Cobra shut down for 48 hours. If he had gone back in the water within five minutes and held the stop, the Cobra would have been happy. But that's not usually something a charter operator will allow you to do. They did, however, remove and replace the battery to reset the computer, but only after a full 24 hours. Good? Bad?
