Pardon me for being somewhat off topic, but that was about a 4.5 second 2BLD solve, except that he had to take a second and a half to put the cube down and start the timer, which probably took more than a second longer than pulling down a blindfold would have taken (even more so if he used nod-don), and that was with him being extra careful in inspection since he knew it would be a good solve, so yeah, I guess I believe a sub-2 2BLD in competition is possible.
