I think we are talking about totally different things, the respiratory rate we calculate has nothing to do with counting breaths, we calculate the sinus respiratory rate, which is a different concept and is calculated through rr intervals.
Thresholds are not calculated through Dfa-alpha-1 and even less with standard values of 0.75 and 0.5, just as nobody calculates lactate thresholds in 2 mmol and 4 mmol, the sinus respiratory rate has a high correlation with the behaviour of lactate, so we can detect two inflection points or two trend changes, through multivariable calculations we can detect the first threshold, assign a heartrate value, watts and a customised Dfa-alpha-1 value.
Breath-counting is not validation of this data.
We will start a validation with more than 1000 laboratory tests.
