This is the track log for Julia from the first day in the same area where I was when I went into airspace. Julia had her Flytec 6030 on the map screen the whole time and she made sure that she was out of airspace:

Notice that SeeYou shows her staying out of airspace just like her 6030 showed her so that she could stay out of airspace. But CompeGPS showed her in airspace. Fortunately it was for one minute exactly and therefore she didn't suffer a penalty.

Lukas also went into airspace that day, but for less than one minute (according to CompeGPS). SeeYou shows Lukas in for one turn, but CompeGPS would have shown him in for a little more. His Garmin Gecko also showed him going into airspace briefly.

Jonny was just to the right of Lukas, and his instrument (a Garmin GPS) also told him that he just went into airspace. SeeYou shows him just staying out of it. What causes these discrepancies is how the airspace definitions are implemented on Garmin GPSes and other non Flytec or non Brauniger devices, as little straight line segments between invisible waypoints.  These straight line segments are a little off the actual definition and therefore showed Lukas and Jonny both in airspace on their instruments.

CompeGPS had its own problems as it draws the circular segment around the airspace at 30.04 nautical miles instead of 30. This adds 74 meters to the radius of the airspace.

Scorekeepers are nearby put on notice about these technical issues and cautioned that they should be very careful when examining tracklogs to determine if a pilot is in airspace or not. Thanks to Wesley Hill for his help with these issues.
