Ive just in the last 24 hours shifted from an AW0 to an AW4 and I've noticed that my Move goal ring is filling up way faster than on my old watch. For example, my move goal per day is 2000 calories. I normally do a half hour walk while using the "Outdoor Walk Open Goal" activity tracker. Today with my AW4, this resulted in 1025KJ Active Kilojoules towards my move goal. However, on my old AW0 this figure would only be 729KJ. Its exactly the same route walking at the same pace. This has happened twice now. What gives?
