at what shutter speed you turn IS off?

LOL
chuck westfall will also tell you the 6D has a great autofocus system. ::)

Happy knowledgeable customers are the most effective sales tool.

a good PR man is always on the job.
IS lenses cost more so he has to promote them in every possible way, always.

does it?
IS needs processing power.
my common sense is not sure what is correct.... could be either.

That processing is done entirely by the lens, not by the camera. That's why IS works the same on any EF mount body, from film through the 1DX. It's also why upgrading bodies doesn't enable new IS modes and better IS performance on old lenses.
So, yeah. I would entirely expect IS to improve autofocus performance. And I'd be astounded if IS degraded AF performance, though I could easily imagine situations where whatever improvement it might make would be negligible.

well... how many photos does the guy shoot a year?
i have read so much crap from him (and i mean the real chuck not the fake one) :)

Not only is Chuck Westfall a very good friend to the Canon community globally, he does stay ahead of the game in terms of what works and what doesn't. And then he has a great ability and willingness to communicate. And it goes back a long way. He was an awesome contributor to the now gone and much lamented Rob Galbraith forums. His prompt technical posts played a significant role in helping a lot of photographers around the planet make the transition from film to digital. And he hasn't stopped giving.
Quite likely he doesn't shoot as much per year as you do, but to flame this guy is a travesty.
