The Coros and Moto g71 G5 are comparable within a couple of percent on distances between 8-10 miles.
The Charge is without using GPS pretty consistent 10 % below these two devices. These runs were done in Seattle.
With GPS it is much more random. My training runs are between 5-10 miles in the same wooded area. It measures 3-15% longer distance than the Moto.
I am giving up and returning the Charge 5.
