Race 2: GPS, cadence and distance accuracy vs previous Suunto models

[Ger43]

@Finnjf said in Race 2: GPS, cadence and distance accuracy vs previous Suunto models:

for a bit more detail (and to rule out one possible factor), were the watches on the same wrist / arm? Was this session (including the warm up) on the track? Just wanting to check that the Suunto wasn’t on the outside (right, if running counterclockwise) wrist vs the Amazfit on the inside / left wrist, which could absolutely swing measurements this way.

Hi, so the warm-up session (the first 3km I posted) was done on the road, while the intervals were done on a loop in a park.
The Race 2 was on my left wrist (outside the track), the Amazfit on my right wrist (inside the track).
But as I said, I don’t consider the interval test very reliable because it wasn’t easy to test. In any case, even in the intervals, as well as in the warm-up, I noticed that the Race 2 recorded more meters than the Amazfit, and this difference was already noticeable during the kilometer.
So far, it’s always been the opposite, although never as marked as last night.
Is there a chance these anomalies will be noticed by a developer or someone at Suunto who can at least verify them?
These anomalies have been reported by multiple users; I find it absurd that no official communication has been received.

@Ger43 You can analyze information from your raw data and compare (export JSON or FIT files). That’s the best way to know which GPS points have recorded your watches and what’s the raw distance vs the official ditance showed in watch.

@Ger43 You can also review your activity data in https://www.sports-tracker.com/ (the old Suunto App website).
In my case, Sport Tracker analysis: Summary shows 10,20km (official distance showed by Race 2) but GPS data and Laps distances show 10,34km as total recorded distance.

With this data:

Official Distance (Device Summary): 10.201 metros
RAW Distance (GPS Points Summation): 10.334 metros
Algorithmic Reduction (Clipped): -133 metros (1.29%)

Official Pace (Reloj): 5:56 min/km
Actual GPS Pace (RAW): 5:52 min/km
Pace reduction: +4seg/km

Why Race 2 is shortening/filtering the distance? Other Suunto watches are more faithful to GPS data. That’s my question, because it seems obvious that Race 2 records GPS raw data correctly, at least is very similar to other watches but, postprocessing is more agressive.
