Good model for boarding

The POLAR Activity Tracker is seen for a class part. The accuracy is the total distance traveled is 99.9999%. Only I do not understand quite the display.
An Example .:
If I run 10 kilometers on the running track, the Arctic shows me these 10 kilometers of well.
But he divided it into: #-standing activity, # go easy, run #

But I'm running these 10 kilometers on 100%. According Polar but just "running 8 minutes' of the whole 65 minutes. Then "go 40 minutes easy" yet and then "are 17 minutes' yet.
That does not fit together.
As I said, the sum of the system is correct. But by this false compilation of course true of the calorie consumption Never.
My Polar Heart Rate Monitor shows here at very different values.
That's why I sent the loop back.
What I also like is not quite the incompatibility with the many apps.
The Polar Loop can only synch with the Polar app. Transfers to other app can not.
That's too bad. I will then take up yet another manufacturer.
