But I wasn't on a tec live aboard, so that is a moot point, as is what you or I consider "deep air". Personally, anything within the recreational limit is not deep air to me, getting to the 50m mark, yes, I start to think of it as deep(er) air.
This is soooo far of the topic it is unreal.
Yes, the Tec 40 only covers up to 50% but look at the limitations of the Tec 40 course. 10 min maximum deco (based on back gas). The EANx 50 is added to provide a more efficient off-gassing process, but the dive is planned to deco on the back gas. Accelerated deco, but for the full time planned for air.
10 mins planned on air, actual requirement on 50% < time on air, actual time on 50% = time planned for air (10 mins). How is that a bad thing?
