Rob ter Horst uses a study of the Swiss Federal Institute of Sports in Magglingen with a cheap ECG device for 1700 USD as a scientific justification to use two Polar H10 chest straps as a reference:
https://pubmed.ncbi.nlm.nih.gov/31004219/
And he ignores studies with expensive ECG devices starting from around 8000 USD refurbised on ebay to devices which costs more than 50 000 USD if bought new for instance g.tec medical.

We are disappointed about Rob ter Horst to use two cheap Polar H10 chest straps instead of the most expensive and high quality ECG device which he can afford.Eventually, he could find friends with expensive ECG device which would help him. But we do know nothing about that Rob ter Horst would search for friends with expensive ECG devices.
We suppose on the contrary, that Rob upsets research institutes with expensive ECG devices by his procedure. Rob ter Horst harms with his procedure our project and our goals.
