Default RE: Windsurfing GPS Team Challenge

Alpha racing is a computer generated category, which is based on a program developed by Mal Wright. The idea is you race either 250, 500 or 1000m, gybe and return to within 20 metres of your starting point. The computer program using your 1 sec waypoints calculates the average speed of your Alpha 250/500/1000, that you achieved with a gybe in it. An Alpha of 20 knots or more is considered fast for the 500 mt category which the competition is using. Check the Swan River Mob sessions, and look at Chris Lockwood's Alpha 500's he's one of the few that consistently goes over 20knts, and compare to other individual competitors.
