Nice to see that some of the info I published is useful to others.

It is important to recall here the recent RAS post from WX about his range analysis findings at the 15m Nats at Yreka.(https://groups.google.com/d/msg/rec....k/AAsFX6OLij4J)
Note that WX had IGC files with 11000 contact point, resulting in a very even pattern and good range.
I consider about 2000 point the minimum to draw good conclusions from the pattern from the Range Analysis Tool.
I updated my webpage to emphasize the importance of having sufficient contact points.

I have had only 2 flights with the V6 firmware that produced valid data. I ran both through the analysis tool. One flight had only 150 contact points, the other about 400. They showed both heavy skew to one side, due to the lack of sufficient contact points.
However, with this limited set of data, I did not observe a significant change in the best range. Was about 6km with V3.4 and still about 6km with the latest V6 firmware.
