Tylerz,
Thank you for taking the time to provide such a well thought out response. What a contribution to the diving community. I hope others follow your example.
I say listen to what Tylerz has to say, he brings up some very good points.
On the other hand, though I believe his response is wholly correct, I think it is too abstract for the average diver to take to heart. I believe that people will not greatly change their behaviour due to inconsistent safety variables.
In other words, people will not stay at home just because their is no one to dive with. Also, although there is no tell-tale sign of when to come up (aka a specific time limit to follow) their is a safe margin for that diver to dive in.
Whether the conditions call for a 3 second dive or a 3 minute dive depends on that diver on that day at that moment. Although we cannot know the exact time limit, we can be conservative and make an educated guess based upon the variables that we do know. By guessing well below our theoretical dive time, based on the conditions, we can provide ourselves reasonable safety.
Although we cannot know exactly what the specific safe time limit is on any dive doesn't mean that the safe time limit does not exist.
The bottom line is, each diver really must decide for himself what is and is not safe. Whether his predictions are right no one can say. But ultimately it is his decision.
Be safe guys, if you MUST dive alone always dive conservative. Remember to know yourself and pay close attention to all of the variables. Beyond that, as always, your safety is in your hands.
