Whats the deal with Zwifts heart rate vs power relationship being so inconsistent? Ive seen threads discussing how Zwifts power estimates are way off, but what about the heart rate data? Is it even reliable? Ive noticed that my heart rate zones seem to be all over the place, even when Im putting out a consistent power output. Has anyone else experienced this? Are we just supposed to accept that Zwifts algorithms are infallible, or is there something more going on here? Shouldnt we be able to trust the data were getting, especially when it comes to something as critical as heart rate? Is it time for Zwift to revisit their heart rate vs power relationship and provide some transparency into how theyre calculating these numbers? Can we get some real data and not just some vague promises of its all good, trust us?
