It's as Jason said - you can't easily get yourself into THAT much trouble quite so easily on a single. You might well have the correct mentality to progress safely, but there are divers who don't.
Example - doing the Elk as a second dive, I was expecting to spend quite a lot of time there - loads of 'branchs on the stern. I'd done a quick, for me, circuit and was surprised to see one of the divers from the boat by the line, agreeing with his buddy to set off to do another circuit. We'd been down for about 15-18minutes, so I asked to see their gauges. Diver "a" had a computer showing 1 minute NDL and diver "b" was showing a stop. I sent them up. In the pub we chatted about it: "And you had just a minute of no decompression time." "Oh, is that wat that means?"
Now if he'd has a twinset he'd have argued the toss about being sent up - he thought I'd sent him on his way because he only had 90 bar left.
