Assuming the bike is a reasonably good model then it'll be far more accurate - your weight deviation from it's set standard isn't going to make too much difference since ultimately it's only your leg mass which is being propelled on a static bicycle.

Sure, it's more accurate than pulling a number out of the air, but what i'm saying is don't go eating back 100% of the calories your heartrate monitor (with it's ~+- 25% accuracy) tell you that you expend... especially if the numbers are relatively low anyway. I'd even go so far as to suggest that some higher-end gym based…

It's not accurate at all really - if you're stressed, if you didn't sleep, too much coffee, coming down with a bug... tons of things affect your heart rate other than the effort you're exerting. Use it as a guide, but don't trust the burn figures as being exact purely because you know your average heartrate for the effort.
