I've been wondering for a while about this one. I always start a dive at the greatest depth, slowly ascending afterwards. Just like in the book. However, It happened several times that I would find myself at the beginning of the dive at 70 or 80 feet for just a couple of minutes, didn't like what I saw, and actually spend most of the dive in the 30-45 feet range.
After each dive, I always double check my computer (Suunto) and compare the results with the tables, as to have a sense of what I can do and not do on the following dive (same day).
I don't use the wheel. It was not part of any certifications I did.
With a regular table, you're supposed to use your maximum depth to make all the calculations. Yet, I can be spending most of my bottom time at a much shallower depth (which allows for more air time and more no deco time). If I just stick to the tables, the third dive of the day is often a no-no, or a very short one. Obviously, my computer gives me a different story since it takes into account actual depths.
My questions are: is there any sense to use the average depth (calculated by the computer for each dive) with the tables? Should I just forget about the tables with this type of dive profile? Should I learn the wheel?
