Race 2 accuracy

@EzioAuditore I am not aware, that anything has been changed in the distance measurement with the recent update.
And I have also seen the Race 2 measuring less than Vertical 2. Just I have not made a bug from this, as I am not sure, it is one. A slightly less distance does not affect me in a negative way. Plus it is not clear, if less is actually wrong…t6, S6, Elementum Terra, Ambit 3 Sapphire, Spartan Ultra Copper, Traverse Alpha, S7 Graphite LE, S9B Ambassador, S9P Titanium, S9PP Titanium, Vertical All Black, Race Titanium Charcoal, Race S Titanium Courtney, Run Lime, Race 2, Vertical 2 Titanium

@Egika I agree. However there are times that the distance is on the ‘bigger’ side. This throws away the pace and the vo2max for example. Another point that shows it is if you use snap to route or navigation, the distance shortening is less but still present. I.e.: route created via strava or SA shows 10.6 km. Running it with SV2 I get 10.55, Running it with SR2 I get 10.4

@Egika There seems to be an agreement on here that it under measures compared to other devices. I would have thought that would at least warrant some testing from Suunto to see if they agree.

Time ago, when I started using Race 2, I opened a thread with my tests and results comparing against Vertical and Race S.
Here is an example, if you want (and have time): https://forum.suunto.com/topic/14375/race-2-gps-cadence-and-distance-accuracy-vs-previous-suunto-models/63The behavior is always the same (and it’s replicable and easy to verify) so there’s something different in Race 2 in comparison to other Suunto watches. I don’t know if it’s better or worse but different for sure.

@jjpaz thank you! I added your information

@Egika adding my N of one, I also find it measures consistently different from every other watched I’ve used (a few from COROS, Garmin, and other Suunto watches, the Vertical 2, Race S, and Race). More telling, though, is those other watches all measure very close to my measuring wheel. The Race 2 measures shorter than my wheel, so in my experience, the Race 2 does indeed measure short. Thanks for your help on this!

@egika Yesterday I tried Race 2 with the new software and the behavior is the same regarding distances and paces as previous software:
Left: raw GPS distance showed (10.17km).
Right: postprocessed final distance showed (10.01km).First one is the GPS data recorded distance (similar to the recorded by other devices and the “corrected distance” by Strava for example. Second one is the “filtered” distance saved in FIT file data and showed by the watch ((tipically the other watches would show 10.16km with the 10.17km raw distance).
First one is always similar in all the devices. Second one only differs (shortened, 1%-1.5%) in Race 2. In every activity, both running, walking or riding the bike.
So it seems Race 2 performs a different data processing than his other “brothers”.
