Also, not all of us are employing a power meter for the sole purpose of getting faster. Mine is primarily a fuel gauge, because I'm generally pretty worthless at riding by RPE. This morning for instance was set out to be low intensity, with the only goals being to have a good time, and try to get home around the 1,000kJ mark. I absolutely cannot do that by RPE. After the 50 brisk miles yesterday, today felt a bit harder than it actually was.
