Height loss during circling with GPS altitude

GPS altitude might be too inaccurate to yield proper results for this performance indicator (using height difference between two consecutive fixes. Maybe a warning should be shown when the gps height is used instead of the baro height.

Individual fixes might not work, but something like least-squares should work. If you're limited to incremental parsing of the IGC files, you might use a simple kalman-filter or low-pass filter to smoothen data.
