This is an incredibly detailed and helpful post. Thank you!
Over the past several months I have been learning SwiftUI, and have started building my own running app for Apple Watch. I regularly use Strava's Watch app on Apple Watch SE, and have found it more reliable than Apple's. Have you tried this?
I'd be interested to see a similar analysis of Strava's Watch app.
Thank you for this blog post. I have a Apple Watch 3 LTE and since a few years I gets worse every update. I usually have around 10% lower total km than my running partner with a Apple Watch 6. If you want to do some analysis I can give you some gpx files from my runs. Health Fit reports usually gps differences up to 30m. My colored tracks look exactly like yours. Glad I’m not alone with this problem.
I would be really interested to hear how you get along with the new Apple Watch Ultra and New Software? Pretty poor of Apple and amazing to see someone going into crazy detail on it.
Sounds like Apple has not sufficiently focused on regressions in old watches operating with limited GPS connectivity. Maybe newer watches can obtain a full lock to satellites faster and newer watchOS versions have started accepting location data earlier when the old watches are not yet operating reliably.

Did you publish your analysis scripts somewhere?
Very interesting. Thank you for sharing.

After watchOS 8, the automatic pause during runs is very inconsistent
Have you tried a new apple watch like 7 or 8?
Looks like the only option is to get a surveyors wheel around your route, mark down each KM and log that split on the app 😉
On a serious note, hopefully this gets some traction!
