Resting heart rate wrong

My forerunner 955 and the Connect app show my RHR as 57 bpm.

Which one? The average 7 days RHR, or the current RHR?

How is RHR calculated if my rate hasn't even gotten that low today?

See here: How Is Resting Heart Rate Calculated on My Garmin Device? | Garmin Customer Support 

Last nightly RHR. Looking at the documentation you provided, it still doesn't make sense because my rate didn't get that low in the preceding 24 hours. 

Please post a screenshot of the page https://connect.garmin.com/app/heart-rate/2026-07-12 

There is a pretty low dip shortly after the noon. If you select that section, the graph reloads zoomed, and you can see whether the 30 min average could have been 57 bpm. Also, do not forget checking the previous day too. The RHR value is the lowest 30 min average for the last 24 hours. It means, if the graph was taken at ~5pm, you should check the data from 5pm yesterday till then.

Thanks. The number said 57 when I checked shortly after I woke up (sometime after 6:52 and before 8:41am), so the dip after noon hadn't happened yet. I had 2 minutes of a 57 beats per minute the day before from 6:12-6:14am, but that's slightly more than 24 hours since I woke up... And only 2 minutes. My heart rate is usually low, but this weekend is an anomaly; that's why I noticed the number seemed off. I think there's a bug. I appreciate your help and you showing me this info.
