Hi Dylan, Im a bit out of my depth here and might not be understanding the question properly, but my gpx file from the suunto gives me the time elements for the data in the file exported from moves count. When you export the gpx file in movescount, there aren't any options on the data being extracted. I think its all managed in the set up of the app that you load to the watch, which creates the datalog file. Movescount has a number of windsurf speed apps you can select from, to get the equiv to the BT31 datalog, so you can get the same data extracted.
