One thing I noticed about HRMs is that often times, they give you a total-calories-burned kind of thing... like if you were doing something for 30 minutes, it would give you the calories you burned TOTAL over that 30 minutes, not the "extra" calories you burned by being active. For example, if I'm doing my "normal" thing for 30 min (typical lifestyle things), I burn probably around 36 calories. So if my HRM monitor says for a 30-minute activity I burned 130 calories, I can assume really, I burned 94 *extra* calories, because 36 of those 130, I would've burned had I not worked out. I don't know if that makes sense, but that seems maybe the case for that first problem?
But that said, HRM USUALLY can tell intensity better than Spark or normal trackers. It seems odd that your HRM would give such a low value for 90 minutes- unless you took a LOT of breaks and weren't actually going that intensely. All hills aren't the same- I've got rolling hills by my house where I cycle, and while they're definitely hills, they're only maybe 3-4% grade; some people cycle at 7% grade, which causes a LOT more energy to expended. Even still, I suspect MAYBE something happened with your HRM and it malfunctioned a bit? The discrepancies are quite large. When I had a HRM, sometimes it would halve my pulse if it was up too high- so even if I was working out and my HR was 170, it would tell me 85. If it's not on your skin tight enough, that could be the problem.
Is your MIO that new fancy one, the type that is just a watch but is a continual-read HRM? I think it's the MIO Alpha? Just kind of an aside question.
