Apple 7 not tracking distance correctly

I have an apple watch 7. I use it for running and it isn't tracking my runs correctly. So far I have tried the following.

Turned all settings on that are required on the phone.
Made sure my height weight etc are all correct
Unpaired the watch and phone and set up as new
Had the watch replaced with another brand new 7
Upgraded my iPhone 8 to an iPhone 13 and paired the watch as a new watch
reset the fitness tracking data

As a last resort I ran with my apple watch on one arm and my old tomtom watch on the other and a friend joined me wearing their apple watch 6. At the end of the run my friends watch and my tomtom showed 5miles. My apple 7 watch showed 4.8 miles. I have contacted apple support who have told me this is considered acceptable tolerance. I am willing to accept a slight difference but this seems far to much. I have also tracked my route online and it recorded as 5miles. Anyone else having this problem or think of anything I could have possible missed?

I wonder if, as you run and sweat, the watch starts to slip around a bit. Try tightening the band. Some have also suggested moving it about an inch or so higher on the arm while exercising.

See the "Make sure that you earn Move and Exercise credit" section in:

You should also make sure your watch is calibrated:

Thanks for your reply. I wear it as high as possible on my wrist. Just below where it bends. I have it one notch tighter when I run so it doesn’t slip and it detects my heart rate fine so I’m guessing it’s tight enough

My wife and I go walking regularly in the summer and our Apple Watches always differ by .01 - .03 miles. We've never worried about it too much as it's only about a 150 foot difference or less.

Thanks for your reply. I have done all this multiple times. Still doesn’t seem to work. I am willing to accept a small error but 0.2 of a mile over just 5 seems a lot
