Cap'n B, he reckons this "George Benson" method. I guess we've all felt ourselves tense up as we increase the picking speed. He reckons that the "George Benson" method uses a position which doesn't naturally cause your arm to tense.

Just done a quick google on "George Benson pick technique" and found a fair few hits on previous discussions on other forums. One of those had a link to this picture of the hand position. So unlike your regular picking position, where you curl your index finger over and then place the thumb against it, this is basically touching thumb and finger together with both straight.
