Jonny Durand's track Log:

This is a display using SeeYou and the "altitude" chart which is supposed to
display barometric altitude. When I use SeeYou to display "GPS altitude" both
instruments give the same values.

The red line is the Flymaster tracker. The blue line is his Flytec 6030. I've
already shown that my Flytec 6030 and my Volirium P1 give the same results.

I've also shown the the Flymaster tracker's track log shows a higher value than
Greg Kendall's Flytec 5030.

This is Kraig Coomber's track log:

The blue line in this case is the Flymaster tracker. The red line is his Flytec
6030.

I have track logs from four pilots. Two from the third task and two from the
last task. Some of the IGC file can be found here:

Also there is an on-going discussion here:

I reviewed some of my other flights at the SCFR and saw the same pattern.

I then checked out some of my flights in Big Spring.

The Flymaster Trackers and the Flytec 6030 produced the same values. Here is an
example:

So why are the Flymaster trackers working correctly in Big Spring but not at the
SCFR?

Is the score keeper taking the data from the Airtribune web site for the SCFR
and not from the Flymaster web site? Does this also explain the drop outs? We
know that the source of the data for the Airtribune web site is the Flymaster
web site and we know that there are problems getting the data from one web site
to another.

We also know that the meet organizers were unable to get the Flymaster Live
Tracking working for the SCFR.
