First: 6 knot current?
SeaJay, I recommend you go to dictionary.com and look into the definition of the word "Hyperbole".
Second, judging by this thread and past ones, it sounds like a number of people don't completely understand how the Suunto computers use the RGBM deco algorithm, and how to properly follow the computer's advice.
Let me preface this by saying, I'm just a Suunto CPU user like a lot of others, and the following is what I've learned from reading the manual and using my CPUs (Mosquito and Vytec). Please correct me if I'm wrong.
Suunto CPUs enter "deco mode" when one or more of your "tissue compartments" is saturated with Nitrogen in excess of 100% (theoretically). When this happens, and the CPU gives you a "ceiling", it's not saying
"get to the ceiling depth asap and stay there until I say you're out of deco", it's saying
"under no circumstance should you ascend above that depth until you've done more off-gassing and I say you are out of deco". A lot of important off-gassing happens below 10' and if you run some simulations using your CPU or Suunto Dive Manager software for a deco dive, you'll see that you can exit deco mode by spending time well below 10' and reducing the nitrogen load on the oversaturated compartments.
To clarify: At any point during a dive, if you go into deco but subsequently ascend and get the particular tissue compartment(s) below 100% saturation, the CPU will go back into regular dive mode, and show you an NDL (no deco limit) instead of the ASC indicator. In fact, depending on your level of saturation, during a simulation, you'll see that the ceiling changes depths based on how saturated you are (deeper ceilings for more saturation).
I wonder how many divers were unintentionally bent because they found that they accidentally entered deco and shot up too fast to "get to the ceiling".
And before you get defensive, SeaJay, I'm not referring to you regarding ascending too fast, because you apparently didn't. But I do assert that you don't understand the "ceiling" concept based on your actions.
