DC Rainmaker explained us how Polar can can accomplish the miracle of extending the running time of the Verity Sense by a only firmware update. But Peter Gamma did not believe in this miracle and answered to DC Rainmaker on his blog, that he can only imagine that Polar has changed the sampling rate of the Verity Sense for this, DC Rainmaker answered to this; «I am tired of refuting our claims»:

Which scientist would give such an answer? DC Rainmaker is not a scientist. He gave us answers like «science sucks», and that was if we remember correctly in a discussion about scientific papers about teh Polar OH1 with the Peter Gamma on his blog:

And Rob ter Horst, post-doctoral researcher at the Research Center for Molecular Medicine of the Austrian Academy of Sciences, Vienna, Austria explained us that ECG devices fail if intense activities with strong body movements are investigated, but not the Polar H10:
And Rob ter Horst’s statement are based on a paper of the Swiss Federal Insitute of Sports in Magglingen published in the European Journal of Applied Physiology:
https://pubmed.ncbi.nlm.nih.gov/31004219/
And this paper was partly funded by Polar. Is Rob ter Horst also partly funded by Polar if he receives Polar H10 chest straps from Polar for free for his tests? Certainly yes.
Rob ter Horst says he is very happy about his Polar H10 chest strap. We are not, since if intense activities with strong body movements are not investigated, 3 channel ECG devices are gold standard for heart rate measurements, which means that these devices are the most accurate ones:
And the paper which was partly funded py Polar keeps silent about this topic, as well as Rob. We as a consequence simply do not investigate heart rate at higher speeds than around 15 km / h, as this has been done in a paper of the Cleveland Clinic in Ohio:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6732081/
to be able to use 3 channel ECG devices of the highest level, and these are those who are used also for clinical and research applications which cost up to 50 000 USD, if bought as a complete package such as a g.tec medical multi-purpose device:
And now we have learned that for our specific application meditation a single channel ECG is sufficient:
And we suppose we can build such a device for less than 20 USD if necessary. Such a device is sufficient for our application meditation monitoring, and we can cite a paper which was published in the world renowned journal «Nature» opon which our statement is based on.
