Glad one of our team got to sail and looks like you have been out a few times , well done buddy , catch up soon

Nice One Justin!

Justin, I ran you file on KA72 through GPS Results and it cuts out any trackpints where your speed is less than about 16kts, so there are no alphas. However if i remove the filters then uses all the trackpoints and calculates the top ten Alphas. I couldn't figure out the filter setting that was causing the problem. Your best alpha was 20.076kts

Justin check your GT-31 set up. Should be like below.
