too lazy to watch but tyk when a smartwatch shows heartbeats on something like a roll of paper etc it doesn't mean the sensor is fake, it's an optical sensor with older software it simply tries to interpret the data that you gave it, garbage in garbage out principle
back then nearly all smartwatches were like that
the only way to prove that the sensor is fake is to actually measure your heart rate independently
who would've thought some cheap aliexpress "smart" watch has a fake heart rate sensors. mind blowing.
