Functions related to HR

For example, without accurate HR data, what cascade will that cause across other functions, such as HRV, Training Readiness, Sleep, Stamina, Load, ect.

I am unsure why you are actually asking, since I guess it is rather apparent (and it looks like you are aware of it), that all those features are based on the HR, so if there is no HR, or bad HR data, then the related metric cannot be accurate either.

Besides the quality of the metrics, with heavy tattoos, also the battery consumption will increase, since the sensor's LEDs will max the power output, in trying to read the pulse.

I recommend wearing the watch on the inner side of the wrist, if there are no tattoos, or having a small window for the sensor laser-erased. You could also disable the wrist HR sensor, and use the HRM-Pro strap round the clock, but that's not really comfortable, and you would have to change the batteries often, at such intensive use.

Who pissed in your cornflakes? Test levels too high? Go for a run buddy. Very simply asking as I am not  exactly sure how all the variables are calculated. Nor could I find this information specifically addressed anywhere other than HR may be faulty.

Thanks for taking time to answer and confirming my suspicions , regardless of how underhanded your response was. Lol

Cool down. There was absolutely nothing offensive in my post. Simply answering your question, sorry if you took it for an offence, it was definitely not intended to be one.
