Accuracy of calories burned on MFP

I am curiuos as to how accurate the calories burned calculations are on MFP, when I plug my workouts in it gives me a much more generous amount then on the machine at the gym......something like 30 min on the stationary at the gym tells me I burned 135 and on here it is like 364!!
I am considering investing in a HRM....how many of you use one and did you notice a better result once you started relying on your HRM rather then MFP or the reading on your machines?
I need to figure something out my weight seems to be at a standstill and I am careful to only eat back about 1/2 of the earned calories so that I am not overdoing it based on the estimations of the website.

some machines calculate calories burned on a average person weighing 150 lbs. MFP takes into consideration your weight

A HRM is great! I have noticed even the machines that ask for weight are wrong, they don't know how hard your heart is working or how much muscle your body has, for example and person weighing 250 with little muscle would burn less that a body builder who weighed the same, make sense?

HRM's are the only way to know what you are burning in calories. The machines will tell what a 150 pound woman may burn unless it gives you the option to put in your height, weight, etc. My HRM was close to MFP numbers on most workouts but not the same. The HRM is much higher than my treadmill. If you buy an HRM I would recommend that you get one with a chest strap. They are not at all uncomfortable and I would say works 99% of the time. I have a Polar F11 and love it.
