HRM/Runtastic Vs. MFP

Well, I've got a bit of a dilemma.

I went walking tonight for about 50 minutes. My average speed was 3.2 mph according to Runtastic. It was like 2.6 miles.

Runtastic is using my HRM as well.

After my walk, Runtastic reported a calorie burn of 440 calories. That seems high to me. I'm 170lbs, 5'8", so just a little overweight. The HRM statistics report an average of 116bpm, max 132bpm, so not too high either for cardio.

However, MFP, when adding walking as an exercise, says that the same time of walking at 3.0mph burned 190 calories.

Those two results are obviously WAY off. I'd love to think it burned 440 calories, but I also want to be true to myself, haha.

So what value should I use? Is a heart rate monitor really accurate for easier activities like walking?

That size, that distance, walking -> ~130 additional calories burned.
