I think we may do more tests this fall. Was just at Williams Soaring Center renting there excellent ships, an ASW27 and 24. The air was very stable and I had high tows to 8000 over the mountains. I also now have a Colibrii II logger so I may have more accurate altitudes compared to GPS only. I may just look at segments in SeeYou and work out the performance using altitude lost over time. This takes wind out of the equasion. I will do the same for flights I have done in the Standard Cirrus if I have some resonable segments. But we had an amazing season in Michigan so most of that data will be totally polluted by volitile air.

Since I did a range of speeds with the older Cirrus tests, it seems I should have found reasonable performance at ONE of the speeds. BTW, Our Cirrus finish looks excellent to me.
