Get to a performance lab and have them do a full analysis on you and determine what you're truly burning when you're working out. I don't believe in anything except what the tests tell me. Everything else is an estimation based off some bozo you don't know.
9% on calibers is very good... even with the statistical % error, it's still very good.

Calories recorded by HR monitor and Energy recorded by my PowerTap - 600 calories over 2 hours would be extremely low. My HR is in the 140s solid for 2 hours. I know it isn't exact, but it sure is more than 600!
I'm actually planning on doing what you suggest - I'm going to go and get the Performance Testing package from Robbie Ventura's Vision Quest. Probably sometime in the early new year. Part of my weight is my build - I'm "solid" (short and squat!), but even so ... I gotta drop some bulk!
