Yes and no. I agreed with what Thal said earlier. It's easy to miss-assess your capabilities for as long as nothing goes wrong. Nothing goes wrong in 99.9% of dives. Thus, it's incredibly easy to over-estimate how good you are.
Getting to the surface safely - regardless of any unplanned issues - is the mark of an experienced diver.
Nothing should be "out of a divers' control" - if they are properly trained, practised and have the experience to deal with it.
The mark of a good diver is how they deal with the unforeseen, rather than their performance on a 'perfect' dive.
As a military guy - I am sure you can appreciate the difference between performance on a staged training exercise and performance under fire. The first does not guarantee the later. Who'd you rate as more experienced, the guy with 10 years of peacetime soldiering in barracks at home, or the guy with a couple of active tours under his belt? The same applies to diving.
Devon - Were saying the SAME thing, I just didn't spell it ALL out. What I stated was that you should be able to get to the surface safely EVERY time. The part I mentioned about the "unless something happens beyond your control" what meant to convey that you should NEVER have something happen underwater that could have been prevented. You should not have an equipment failure because you should check your gear at ALL times to ensure that it is "clean, dry, and serviceable" at a moments notice. If something does happen underwater even when this is performed diligently, then I consider that out of your control. The statement was made with the presumption that even if THIS happens than you STILL should be able to get the surface safely. I was implying that the equipment failure, or something else entirely, may happen that has zero to do with the diver or their abilities. And when things like this DO happen, which inevitably they WILL lol, you need to be able to get to the surface, even with all this going on.
We were definitely saying the same thing but I prefaced the statement with understood commonalities of an experienced diver - mainly being able to get safely to the surface withntheir buddy at ALL times (DESPITE, or in accordance with rather) irregardless of unforeseen or unplanned emergency equipment failures or Murphy's Law playing games with you

How's that Sir
