I'm sorry, I just don't get your point. Surely we were all taught that such ascents are risky, and I'm sure the rescuers knew it at the moment - but being heroic requires risks at times. With no deco obligation and minimum nitrogen loading, it sounds like it was a minimum risk really - but getting her to the surface was extremely important.
I think he meant that you have to consciously take certain factors into consideration and make a judgement call. TGIF858 made a judgement call based upon time at depth, Nitrox mix, and the immediacy of the situation. Those of us on the boat were all told to keep an eye on the rescuers for any signs of DCS.
I think Matt's words of warning were meant to say "just because you've heard of some divers ascending 80 feet in 30 seconds without problems doesn't mean it's always a good idea in every emergency." Take ALL of the factors into consideration. Make the judgement call but realize that you're willfully taking a risk for the greater good, then do something to manage that risk (such as having people keep an eye out for symptoms).
In the case of this rescue, I absolutely agree that a rapid ascent was the way to go. And yes, it saved her life. However, other scenarios may differ due to the variables involved.
