Recorder app speed graph is consistently off

The Recorder app's built-in speed graph always overestimates my speed. I can tell it's unrealistic, and it doesn't match up with the speed value I get from the GPX. It said I was going like 5MPH walking. If it was KM/h it would make sense, but I'm not sure why it would do that.

That's odd - maybe you could post a screenshot of the graph for something short, the actual recorder storagefile (using the IDE) and the GPX file?

The calculation is done here: https://github.com/espruino/BangleApps/blob/master/apps/recorder/app.js#L383-L401

But it does do some scaling here based on your current locale's settings, so that might be it? https://github.com/espruino/BangleApps/blob/master/apps/recorder/app.js#L368-L370

I actually deleted the logs I had, but the next time I use Recorder I'll post a follow up.
