Which HRM subtracts BRM?

I emailed customer support for my NewBalance N4 HRM about whether the calories burned already had my BMR calories subtracted. I was disappointed to get an email response saying it didn't. I know I could just do the math, but does anyone know which HRMs subtract your BMR from the total calories burned?

EDIT: Total typo on the Topic Title... grrr.

    are you wearing your HRM all day? they aren't designed to be accurate for anything other than physical exercise.

    Whatever you do, do not get a POLAR HRM!! I have had 2 and they both quit working within or less than a year and their customer service sucks!! I am hoping this one I have will limp along long enough for me to get my money's worth out of it. It did not factor in BRM either......

    Just FYI!!!

    For starters, it is my knowledge that all HRMs go it the same way. They give you total cals burned for the duration of exercise. they have no idea you are going to use those numbers and plug them into a program, such as MFP, that already gives you an allowance for maintenance. Which brings me to my second point.

    BMR is the cals you burn in a coma, if you did not exercise you for that duration you would burn more than BMR, therefore you should be backing out maintenance calories, not BMR, as MFP bases your caloric goal on maintenance, not BMR. So if you are sedentary and your BMR is 1600, your maintenance would be 1920, a difference of 320 cals/day or 13/hour, not a bid difference but enough that you should account for it. So if you worked out for an hour you would take an additional 13 cals off if you used the proper maintenance vs. BMR. If your BMR or activity level is higher, then the difference/hour will be larger.

    How funny.. thousands on this site by Polars everyday and have no problems with them.. so don't assume that they all suck because you had a bad experience.

    To OP:
    No HRM backs out BMR calories... and personally, I never adjusted for it either, and lost weight just fine.

    HRM's when used in steady state cardio and have all info(age, weight, height and gender) can be about 80% accurate I've read. If you add in Vo2max then I belive it goes up to about 90%. Since there is a 10-20% margin of error anyway, I wouldn't want to mess with it.. so I just never did.
