I biked 9 miles with the Google Pixel Watch 3 vs. Samsung Galaxy Watch 7 — the results surprised me

That’s really close enough. Reading this article really makes me miss Galaxy Watch. I’ve switched to apple and it’s not as satisfying experience.
 
I applaud your determination to get the comparative results and doing the long ride again. However, I see you have no established baseline to compare these results against. In other words, how accurate are the results put out by G/S watches compared to what the more accurate values are? You get the actual values by using calibrated medical equipment strapped up. They all may be fairly close, but without a baseline, any testing is not a valid test,IMHO.
 
Hi Dan,
The difference in average speed - 11.5mph/Pixel 3 and 12.3mph/Galaxy 7/Strava - seems very wide, roughly 3.3 minutes over a 9.5 mile ride (49.6 minutes vs 46.3 minutes). Could it be that the Pixel was measuring total time while G7 and Strava were "pausing" when the bike was stopped, maybe at traffic lights? If this is not the case, am wondering how/why there would be such a large discrepancy (~7%) for a simple time and distance calculation.

Thank you for the review!!
