After Peter Gamma from www.petergamma.org
wrote his review about consumer grade heart rate monitors:
hardly any new scientific papers where published about this topic. And basically only one scientist seems to remain which is Rob ter Horst who tests all the consumer heart rate monitors:
Does Rob ter Horst screw around on his heart rate data until they look nice? As Molecular Biologist Isidro Ballard did screw around on his data in Zürich in the 1990 in Charles Weissmanns lab, before he killed himself?

If Rob ter Horst is the only scientist who who scientifically studies the accuracy of smartwatches, and if this is also co-ordinated with smartwatch sellers, is this not another violation of competition laws? And will kill Rob himself too, if these things are true and will be published in the newspapers?
What is striking about the papers that there is basically not a single paper which uses the same protocol as another paper:
And as a consequence data from one paper cannot be compared to data from another paper. Was this done on purpose and on request of smartwatch sellers? Are not many of these things co-ordinated by for instance a marketing software? And if so, is it not a clear violation of competition laws in the US, EU, UK, China, Canada & Switzerland? According to Rob ter Horst, the latest Apple watches should be the most accurate devices on the market. But this has not been proofen in a scientific study which is published in a scientific paper. The Cleveland Clinic has testes Apple watches in two papers, and then stopped testing. So there are no data for the latest Apple watches from which we would know about it.
