It sounds to me like they are living in the past. As more evidence comes in it certainly seems that lower is better. I know a lot of Richard Bernstein's evidence is anecdotal, and his views on many things are quite extreme, but you can't argue with results, and he tries to get all his patients into the 4.5-5.5 range.
The ACE and other medical organizations are now saying that 6.5 should be everyone's (Maximum)target. I think only the ADA is still saying 7.0 is OK (and medical professionals who have been listening to the ADA for the past 20 years)
I say good for you with a 6.2, keep up the good work

. It is my understanding that having lots of Hypos causes Hypo unawareness, not running 'normal' blood glucose levels.
