Garmin uses the New leaf method where you get a vo2 test and enter y,our data as a base line. This is the most accurate. If you don't have a vo2 test done, it then uses the first beat algorithm 1st or 2nd gen depending on the device, and is claimed to be accurate within 10% for 2nd gen and slighty less accurate for 1st gen.
Here's a good write up explaining their methods.

Yeah I read that the other day.
Still, strange that they would be 800 calories out. Even a simple online calculator is within 100 calories when I put in my weight and time biked.
