Ucarkus, First, I apologize. Not everyone has the same sense of humor (some have none) or understands sarcasm the same way.
You said:
I think your point is that if a person can do a CESA from 15m (even though the training -- if they've been trained for a CESA -- is only from 6-9m), that they are within range of the surface for a lot of their dive. You may as well have said if a person can do a CESA from 18m (max recommended depth for an OW diver) then they are within range of the surface for ALL of their dive. What is magic about 15m? It is neither the CESA training depth nor the recommended dive depth.

To which I replied, sarcastically:I often get average depth of 15 meters when doing recreational diving even max was 30-40m. This means in average I am within the range of the surface..
You said:Cool. That means on average you won't die. Great plan.
To which I replied, sarcastically:It seems to work.
Then you said, clearly missing my humor:You mean, "I haven't died yet." ?
By the way, when you say "50% of the time" you are referring to a median, not an average; the two are different, in general.Looking at how strange your response is, I take it that you mistook my comment. Is anyone diving without redundant gas is suppose to die? I am just pointing out that in reality 50% of the time you have direct access to the surface within your basic owd training.
