Shed and Shred calories burned??? Help!!

I am pretty good at estimating calories burned while running, but I also do Jillian's Extreme Shed and Shred and I always have a hard time figuring out how many calories I burn. I'm 5'4" and 146 lb. Right now, I have my diary set to record 500 calories burned in 80 min of doing the workout. I WAS logging it as 600-700 cal but that seemed a little high...Anyone?

I usually log it as circuit training.
