Move IQ Walking

Hi,

I went for a walk 7:40 to about 8:50. I stayed a lot of times and threw ball with my dog. Move IQ only registered that one hour walk (little over one hour) like ten minute walk from 8:40 to 8:50. Does Move IQ only work if you walk all the time and don't stop? Is it normal that the intensity minutes is 13 minutes after that walk?
