I've just noticed that ThinAirDesigns, one of the USDC "Blackbird" team , has posted on another site that they have heard "from the highest authority" at NALSA that a speed of 2.8 times the wind speed will be ratified.
There were faster runs, but some of these were at times 500 feet from the nearest wind speed sensor; the 2.8 run was never more than 100 feet away, so the wind speeds can be regarded as accurate. Nothing yet published in writing, but it should be very soon.
