I think measuring one's VO2 max or at least their pulse post exercise would be most accurate to test the level of stress that was place on one's body than calorie burn. Exercise aside, how do doctors conduct a stress-test on a patient? They don't measure their calorie burn. I have yet to see an exercise assessment that looks at one's calorie burn as a means of measurement and I've been required to review many of them.

Would the individual with the higher peak and mean heart rate have a higher burn, even if the range was wider than the individual with lower peak and mean hr, provided both performed at the same perceived level?

I have no idea. I'm roughly 3/4's of the way through my MS program and will have my PES at the end of this semester and I have yet to study any evaluation method that looks at caloric expenditure. Heart-rate, VO2 max, yes, calorie's no. Is there a correlation between the two... maybe, I just haven't been exposed to that. I don't know how you can measure caloric expenditure accurately outside of a controlled lab environment for all types of exercise.

No yeah, that's fair. Reason I ask is, at a basic level, that's what our HRMs are doing. There's more nuance to the data, and processing of it. But essentially it's taking the heart data, deriving an upper and lower bound to find range. Then comparing mean of the data set after different time points and comparing to known data that correlates lab burn to heart rate.

Then it probably normalizes the data across the workout time by applying a caloric expenditure and treating it like a per minute mean.

Or at least... that's what I think would probably be easiest if you had access to multiple data profiles and such.

I am leery of those, doesn't mean I'm right. One of my professor's, who is an f'in research Nazi, recommended this Podcast called "Guru Performance! We Do Science." It's run and supported by the ISSN and the have guests that have PhD's and experience in various aspects of fitness, nutrition, physiology, bio-mechanics, etc., and one guest was talking about HRM's specifically and said they can be off by as much as 25%. For somebody like myself that eats at least 3000 cal's for maintenance, that's a variance of 750 calories which is significant. Granted calculating calorie needs and even the calories found in food are all a bit of a swag. I just prefer to take out some of the "swag" where I can and for me that's counting calorie burn. Heart rate tells you what you need to know.
