Using Garmin forerunner to track calories burnt

So I used my Garmin Forerunner with HRM for Insanity today morning and plugged in the parameters into this site - http://www.triathlontrainingblog.com/calculators/calories-burned-calculator-based-on-average-heart-rate/ Turns out that I have burned about 600+ calories than my estimated 300 odd calories. How accurate is this?

    That seems pretty high. But it depends on your weight/age/fitness level

    Im 34. Think im pretty fit. (Not s newbie tobexercise) 143lbs. I burn about 340 in 44 min
