Walking outside and km per hour

[fa.ce]

I'm lovin my AW more and more using it extensively
i've calibrated for walking with my iPhone 6 plus
But having a strange issue (?)
I've walked out and it shows 10'13" km in steps section.
In effect i've walked at about the half shown in steps sections (5 km per hours), as shown at the end of session.
Why then steps section during session shows always doubled values of about 10'xx" km per hour?

The values fluctuate during the exercise and I've also found it to be a bit inaccurate. Perhaps I need to re-calibrate for my running but its of from anywheres from a 1/4 mile to a 1/2 mile depending on my run (the variance increases when my run increases)

I believe that is your pace, 10 minutes, 13 seconds to walk 1 km

+1. The watch is showing you pace in minutes per KM. (It is not speed in KM per hour.) Walking and running are typically shown in pace while faster activities like biking are shown in speed.
