It's common in "debugging" situations that people only report the information they think is important. I like to see "everything" because what people think is important often isn't.

It seems like that's the most likely explanation. Maybe, the lake was a reservoir? I don't know if the orbital scans of topography read water surface or not.

Well I was finally able to figure out how to download a tcx file, but it took a bit of doing to convert to csv. The data show a baseline of 74 meters, corresponding to when I was in the middle of the lake, rising to 98 meters at a point close to shore. Since the nominal lake level above stream bed is 28 meters, this seems to match my experience. Yes, the lake is a reservoir. I could probably upload the csv file if you want to take a look.

No one uses these to determine elevation gain on flat water. It's not too surprising that this use-case doesn't work very well.
