I clearly hear and understand that advice and even agree but since it is all that I have to go on, I figure it's nuances in error might be consistent enough to use as some sort of gauge, even if inaccurate. I run 2 programs for every ride, they never agree on anything, not even distance. Sometimes off by over a mile, esp if Mtbing. That might be the way the program calculates valleys, dips and such as a straight line rather than down the incline and back up, IDK.
I once ran Strava on my GPS and phone, and still got different results, so ... lol, it is just a simple tool to get basic information. If I was a more serious cyclist, I would invest in better equipment.
Thanks for the heads up info.
