Calories Burned Estimate using average heart rate

I found this formula on the internet:

C = (0.4472 x H – 0.05741 x W + 0.074 x A – 20.4022) x T / 4.184

Where C = Calories Burned, H = Avg Heart rate, W = Weight, A= Age and T= Time (in minutes).

I'm confused about the Weight variable. I was under the impression that a heavier person will burn more calories than a lighter person doing the same activity. If you plug in a heavier weight the Calories burned actually reduces. The only thing I can think of is that perhaps this formula implies the heart rate of a heavier person will be higher for the same activity?

Any thoughts? Not sure if this has been discussed previously on here.
