What sort of estimates do you get from the 5X?
Looking back, I must have been high, or something. A "mall walk", using the 5x, and a calibrated footpod, (I know it's calibrated correctly, we have an oval here that was used in the Winter olympics, and the track is calibrated to the .01 mile per approx 1/4 mile (442 meters) ) and I get for a .51 mile walk, at 28:18 min/mile pace, Average HR of 104, and it was 89 calories. Another "mall walk", this time 2.23 miles, 23:03 Min/Mile pace, 51:18 minutes, and Average HR of 118 gives 341 calories. Once again, using the calibrated Footpod. I have compared the AW with known mall distances, one is approx .91 mile, the other, (the latter walk above) is approx 1/2 mile around, and the watch closely coincides with what I get from the Fenix. I must have been thinking with the left side of my brain, I need to do a few more outside walks, but I think I "may" have been mistaken above.
