Except that if there's new evidence showing the figure is lower, let's see it :)

The measurements we have made show 0.07% over the past month or so, the figure being users who can access a site with an A record, but not one with an A and AAAA record.  There are still corner case issues out there, but I suspect that that small percentage may well be down to users who don't update their OS or software.  It would be very interesting to know the real causes.  I would hope things like 3484-bis and happy eyeballs will help reduce these further.
