Incorrect assessment of hrv

[RZJ]

this morning my Fitbit tells me that my readiness is low, based on my hrv being 39% lower than average. It also tells me that my hrv is 31 ms, compared to my average of 26 ms. This doesn’t make any sense to me. Am I misunderstanding something?

Hi, @RZJ , your Heart Rate Variability (HRV) is only one factor taken into account to create your readiness score.  Other factors include your recent sleep scores and your resting heart rate.

For more information on how your daily readiness score is calculated, please see this help article

I understand this. What I don’t understand is why the app tells me this value is lower, and then shows me a graph, and number, that is higher than yesterday.
