And here's what make it even more puzzling to me now. I rode my commuter bike today and took the Bolt with me as I usually do, wore an HR monitor, but didn't have the PM pedals. This time RWGPS completely overestimated my calories IMO, reporting about 1500 calories for what I consider an easy ride. On the ride I did with the power meter a few weeks ago at the start of the thread I was pedaling hard and getting a real workout, and RWGPS reported half the calories for the same bike time. Yea, it all nets out, but that's not my point. Why is it so inconsistent?
