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
