Walk activity distance short by about 7% since 12.25

I have several trails near my house I've been using for my morning Walk activities. Since I walk these trails often, I know the distances of various points along the path of these trails. After the 12.25 beta firmware, I noticed shorter distances along the trail and a total distance which is about 7% shorter than my previous Walks. My Walk activities distances with FW 12.25 were 5.86 and 5.89 km. My previous Walks on the same trail in July with FW 11.12 were 6.26, 6.27 and 6.26 km. Previous Walks of this trail with my Fenix 7s resulted in 6.24 and 6.27 km. This morning Walk activity with FW 12.27 on another trail yielded a similar 7% shorter distance (about 0.5 km short on an 8 km walk).

    Silly question but is it using GPS? and was the GPS setting the same? Does the track on the map look similar? sometimes the FW update changes some of the settings.

    I have not changed the GPS settings. I always use the "All + Multi-Band". The Track on the map looks identical (within reason).

    wow. that is very strange. i wonder if you have taken the time to just manually go over the course to see if that 7% is just slowly accumulating or there perhaps is a particular segment of the route which is grossly different between the different FW version activities. (eg, just looking at where 1km, 2km, 3km, etc are on the map)

    The distance is "slower to accumulate" than in previous SW versions (and the Fenix 7s). In fact, the first time I noticed that something might be off is when I reached the 0.5 km road intersection and the distance on the watch was unusually short. At first I dismissed it, but then realized that the walking distance is shorter in a "linear" way.

    I went for a walk today with both the FR955 and the Fenix 7s SS. The good news is that the distance is back to normal on my FR955, so the problem I had last week is unlikely to be Firmware related. I am still puzzled by the short distances of last week. It was too consistent, for 3 days in a row, to be an operator error. The only thing that comes to mind is that the previous Walk activities prior to last week, were several walks I took during a Svalbard Expedition. I am wondering whether the high northern latitudes (nearly 80 deg N) activities had some effects on GPS and Walk distance calibration that carried over to some of the future walks.
