Polar FT7 HRM overestimating my calorie burn?

This makes sense and is what my trainer was telling me this morning. He's really interested to know how many calories I'm burning because according to him, I'm training at a higher intensity so he thinks I'm buring btwn 700 and 800 calories, and MFP says it's between 450 and 550; that's a huge discrepancy. Like a two-glasses-of-wine discrepancy. I'll have to invest in a heart rate monitor to be sure.
