Lefty tighty. Get it righty.
It's just that using the GPS now so ingrained in what I do it has made itself indispensable. That's just me. Others get by fine without them.@Dogtrousers .. you wrote in another thread that you found your GPS device (presumably a Garmin) “indispensable”. Mine is at best (so far anyway) a “nice to have”. Could you please expand on why yours is so important to you? – perhaps I’m missing something (functionality that I’m unaware of, maybe).
Sure I could live without it. But I like being able to plan detailed routes of a specific length and then not have to worry about navigation at all once I'm out on the road. Others like to wing it and go without a plan. Others like to use paper maps. Vive la difference.
Consistency is all you can ask for. How would you be able to tell whether it was right or not? What would you compare it with? There isn't really any way of getting a gold standard for total ascent. Various methods exist and all differ a bit. If you choose one and stick with it then that's fine.Elevation (total ascent + total descent) … tested on all bikes and it comes back with consistent results (whether the results are right is unknown but I’m reassured by the consistency).
Mind you Strava was much more generous and gave me another 607 ft
