And these deliver data which cannot be reproduced? Are the scientific tests of Rob ter Horst worth nothing? Again and again Rob ter Horst makes scientific tests about smartwatch accuracy:
But if we go to the scientific literature:
https://petergamma.org/90-review-of-accuracy-studies-of-consumer-grade-heart-rate-monitors-methods-testing-protocols-reference-devices-02/
Are there only people who do scientific smartwatch accuracy tests who screw around their data until they look nice? Since these tests cannot be reproduced? Since none of the testing protocol of one paper can be compared to the other. Was this done on purpose?
And is the Polar H10 chest strap is also another miracle which his hard to believe, as presented in th following video:
What we have learned that scientists do basically only heart rate tests on treadmills up to around 15 km/h.
At higher speeds we do not know of any good data, since of problems with ECG motion artifacts.
And scientists use 3 channel ECG devices which are gold standard for heart rate measurement, as explained here:
In the future we will ignore scientific tests about smartwatch accuracy on YouTube. And we are only interested in 3 channel ECG devices which are gold standard for heart rate measurument on a treadmill up to around 15 km /h..
And we are only interested in information which we find in a
scientific library such as this one:

And will we not find Rob ter Horsts smartwatch accurcacy tests sold by Vedia Switzerland where cheap products are sold for a cheap price?
