have you noticed that the grade showing on the edge as you ride is very different from what uploads? 22% becomes 16%. 20-22 was probably closer because all other 16% I can ride but could NOT on that one!

What about difference in HR? On the edge before upload, it reads 140(I was pushing like crazy the whole way and I am almost 60). Upload shows 130. This happens often. Does anyone know why? What about MB gravity? Do you use it? I stopped applying it because it adds about 200-500' depending on ride.
