Really? You (and whoever "we" constitutes) are the only person in the world I've ever heard use the term "210 mix" for air. 'Course I've only been around the diving community since 1961, and I may not have been paying all that much attention.It's not private code... we go into a shop at a remote dive site and ask for a 210 mix... "Air, please."...

Everyone can start throwing darts, but I remain unconvinced that I truly missed 30 minutes of deco.
Again, I respect everyone's points and I understand that the real issue is adjusting my behavior to avoid deco. Message heard and agreed.
It is very unusual that I dive with just the Wisdom. I have Orca Pilots (Nitrox version) that I use as backups. As far as the Wisdom being less conservative than other computers, I'd have to say the Orca is even less conservative when in the normal (0) mode. The Orca has the capability of adding conservative factors; I have not found a similar feature on the Wisdom. My typical method of diving the Orca was to maintain 2 digits of dive time remaining. If I got to 1 digit, I ascended - typically a major step - in the range of 20' if possible. That practice was a carry-over from the Edge days of staying 2 pixels above the line (which was partly a carry-over from multi-level dive planning with tables).
That practice does not work effectively with the Wisdom as it incorporates air consumption into the mix. My dives are typically governed by air consumption, not deco. I find this an annoying aspect of diving with the Wisdom and may be a contributing factor in getting lax. I am likely to go back to a computer that monitors deco status only.
Sherwood Scuba is very concerned about the question posed here. We are very glad that nobody was injured. Based on what we have seen, it does not appear the computer malfunctioned. We have sent wetlens a private message to get more specific information to resolve this question. This thread has proven a few points. Many divers dive many different ways with many different types of equipment and we all have our own opinions. No one piece of equipment will work for us all and we all must determine the type of diving we will be doing and the best equipment for that type of diving. Diving safe in whatever environment we are in is the most important aspect. Learning more about how your equipment works is part of the safety aspect. We will get wetlens answers and post the outcome so we can all learn from this. In the meantime, read your computer manuals, utilize any simulators, take any classes, pay attention to warnings/alarms, review your dive plan before entering the water on mulitple dives, know what to do if the limits are exceeded and just be safe out there.
Safe diving,
Sherwood Scuba
Mostly what it taught me was to pay closer attention to my computer, don't push the limits, and don't go into deco.
I've done over 100 dives with it since and never crossed that line again. I'm a rec diver and deco is for techies - I can't imagine actually PLANNING to hang around on a line at various depths just breathing gas.
So, I am also interested in hearing Sherwood's take on this incident.
