Polar FT7 calories burned vs. what the website says

I just got the Polar FT7 HRM two weeks ago, and I manually input each workout onto the polarpersonaltrainer.com. I love it, but I am not sure why the number of calories burned on the watch is different than what the website lists.

Today for example, I was on the elliptical for 60 minutes. My Polar FT7 told me my average HR was 130, max HR was 139, and I burned 489 calories during that workout session. Cool. I enter this into the polar website and it automatically bumps up my calories burned to 705. I can't figure out why the HRM and the website track different calories burned for the same workout, HR, everything.

I tried searching for reasons online, on the polar website, everything, but can't find anything definitive. It's a little frustrating. I've been tracking the calories my Polar FT7 comes up with, as opposed to the inflated number from the polar website.

Does anyone know why this is happening?

I have a similar problem. I was on the eliptical for 10 minutes yesterday. The machine says my calories burned are 153 while my FT7 says it is 98. when I inptu the time on MFP it is similar to the machine.

Ok it is only the second time that I've used the FT7.
