Sole E35 Calories Burned

Minihill

So, I've been using the Sole E35 elliptical for awhile and for 90 min. it says I burn around 1200 calories. I use an incline of 18, level 14, avg RPM of 64, go about 6.6 miles, and an avg. speed of 4.4 mph. I'm 5' 2" and 130 lbs. I wanted to know if the machine is giving me an accurate calorie amount. It has my weight and age in it too. Thank you!
