There was an accident and incident post here last year of a diver who found a woman w/ no mask, hung up on the reef by a taunt reef hook in heavy current. It was speculated that she turned her head to look back and the current swept her mask from her face.
So this in my mind says that there are certain conditions where you can lose your mask and have no buddy in sight AND you don't have to be on a tec dive for this to occur.
It also made me drill even harder to get any student I work with to be able to swim maskless without holding their nose.
If you do lose your mask you should be able to make a safe ascent unassisted should the need arise. You may have to hold your gauged up to your face, squint your eyes, or reference your bubbles. It doesn't have the 30ft/min per say, but you shouldn't be rocketing to the surface with your eyes shut either.
There are worse things than squinting your eyes open in a pool. Try it in cold water w/ 2 feet of viz, during a red tide w/ sand particles surging about. That hurts.
