Nice work here, but really though I find that cadence is more about 'comfort' than trying to be 'efficient'. I feel that if I'm pushing a comfortable pace, around 100 or 110, I'm working pretty efficiently BECAUSE I'm comfortable. What I'm trying to say is that cadence and whether a higher or lower one is more efficient, it depends on what you personally find comfortable. But regardless, good work. We always hear debates on cadence and efficiency/heartrate...
