This was one of the most significant things I learned and changed in my training after getting a powermeter. I'm not sure I ever pedaled for more than a couple of minutes at a time prior to that. All those little seconds of coasting don't affect hr too much, but it's instantly noticeable with a power meter.
Took a year or two to really get used to it, because it definitely does a number on your legs when you're not.
