SV clocking a 7.9mi loop at 8.15mi. Is this the general margin of error with Suunto?

@zhang965 I don’t care about added values. Its a forum after all not a scientific publishing platform

It’s why you are not Suunto’s target audience.

@zhang965 is this your idea of entertainment? thought you found greener pastured on Garmin - how is the Garmin forum?

@Hristijan-Petreski Interesting as my AWUltra is often less distance than the Vertical and I think (I cannot be fully certain, maybe I should test the loop I have used a wheel to measure distance) the Ultra is measuring short.

Garmin’s forum is boring, less entertainment then Suunto community forum.

So you’ve already been banned over there, aren’t you luv.

@Andrewx01 I faced the exact same issue. I have a Garmin 965, COROS apex 2 pro, Apple Watch 8 and I do wear my vertical together with the rest of my watches just to test out the distances. The distance on my Vertical will invariably be clocked at longer distance , ie for a 10km run , it will be 200m longer for my vertical compared to Garmin 965 and COROS apex 2 pro.

When I use software to zoom in to the tracks, I can then understand where the extra distance came from as vertical tracks are more often zig Zac compared to the rest and I figured that must have been the reason. However, it seems vertical has the most accurate distance count by the experts. So I guess it should be.

My vertical counts less distance when I run a little bit fast,; if I walk, it gives almost the same distance as epix2pro.

I saw Suunto’s tester was running at 16mins/km to proof the good gps tracker, sadly I cannot keep running in such a pace.

Have you tried run slower to see your vertical gps performance?

@Andrewx01 IMHO the matter is quite simple. For example, if you take a perfectly flat road and measure a distance of 1 mile, a watch that measures the GPS location every second will make a tiny error in each measurement. If you run a mile in 5 minutes, that’s at least 300 locations and 300 small misses. The algorithm (and each watch manufacturer has different algoritm) compensates these small errors, of course, but in the end there is still a deviation from the measurement in a straight line and the calculation of the path after 300 locations. In your case the error is around 3 %, which could be smaller, but it could also be larger

@Brad_Olwin Yes usually my AW gives me less distance too from cold start (their not so clever implementation to start the activity within 3 sec might be the case. So what I usually do is start an activity stop it after 5-10 sec - delete it and start again so the GPS lock should be much better).

@zhang965 walking will definitely get more distance as the gps track will not be smooth and is more zig Zac.
