When you talk about "ride data" and recording ride data and having various sources workup that ride data you need to really understand what all that means. It may well be that the ride data, in terms of the track that was followed, is simply the gps track itself. "Tracks" and "Routes" are nothing more than a large collection of latitude/longitude pairs. Even if you're transferring ride data that contains elevation, or other associated data, the destination software may only use the lat-lon data(plus time meta data) and then use their own data(sources) to work up other metrics as needed. While the lat/lon points(+time) are unique and transferrable, the remaining output can & will vary depending on data sources, assumptions made, and software(algorithm) processing. Mapping data sources are somewhat a commodity and they do vary.
