Anybody has an idea where the recommended maximum 6.3 g/ℓ for gas density comes from? As far as I know, the recommended maximum is not 6.3 but 6.2, according to the research by Anthony/Mitchell.
 
Hi Guys, those of you already having access to the new Tec Rec standards, please be kind enough to state the maximum depths allowed for training dives about emergency ascents with a responsive diver (share air) and irresponsive diver.

Well, that is quite a review.

I retired from teaching last year. This review makes me sad that I will never get to teach this program.

I assume PADI found it simpler to stick to a round 40m on air, consistent with previous advice, rather than trying to adopt 39m.

I believe the simple explanation is that the recommendation is “less than 6.3” not “less than or equal to…”. Now working with single digit decimals it pretty much implies 6.2…
