HIIT and HRM

Hi guys,
I finally broke down and got a HRM, and as expected, I find that my hour workout burns about 500 calories rather than the closer to 600 that MFP calculates. However, half of the workout I spend doing HIIT, which I know is supposed to burn more calories than more level cardio. However, I suspect that the HRM does not account for that, right? It is just doing some basic math with my height, weight, and HR, right? Surely there are more actual factors involved? I'm planning to just go with what the HRM says, but I'd like to hear what people think of this.

    I think MFP numbers are a little to inflated, When I run I use Map My Run, and it gives me a figure, then if I put the same info on MFP it gives me another figure off by like 100. don't know which one to trust.

    In exercise, always go for the lowest calorie burn and hope for the biggest.
    In food intake, always go for the biggest count and hope for the smallest.

    This way you are not overestimating anything.

    Thanks guys! After reading a bit more it seems much of the benefit from HIIT is from the 24 hours after as well, so the numbers are probably pretty close. I'm going with the HRM.

    That's not correct.

    Back to your original question, HRMs will considerably overestimate burn numbers for HIIT type training. Start by cutting the number it gives you by 60%.

    That's what I do.

    Do you have evidence for these claims?
