Perhaps these could be the number of satellites to visible, locked, and used?

I doubt it, since the value is always 2 From byte 5 these are very confusing parameters. Maybe some kalman filter parameters... Apparently when uploaded, the ttbin GPS data is filtered, since lat/lon values on TomTom Mysports (e.g. when exporting from Mysports to GPX) do not exactly correspond to the raw values in the ttbin file. In order to match e.g. track distances on watch and TomTom Mysports, information must be passed on the filtering. Hence this assumption...
