This is the kind of silly crap that passes for knowledge. Actually, training with all the types of biofeedback available is the best methodology. Using "power" as a single measure of applied training stress does not preclude the benefits of other information.
I train with power but I still observe my heart rate (although many people will tell you that they don't), but my point is that heart rate is affected by many factors. One is of course fatigue but the others can raise or lower your HR for the same "performance" or "work". You may even have different heart rates but the same power and RPE.
FWIW, here are two identical rides from Monday and Friday. Nearly the same time and power, but today was a higher HR. It didn't "feel" any harder and I have about the same amount of residual fatigue. They are both recovery rides so neither is "well rested". THe only appreciable difference between the rides is that on Monday it was raining and the path goes down into a creek, which was closed so I had to detour a bit at the very end of "lap 3"
note: you have to ignore the "max speed", it gets spikes but there are corresponding down spikes and the averages work out.
