That seems like a waste of money, what exactly are you going to change? You already know what is generally disturbing you/your hours are not great or whatever, so why stats to track it?
But now we can stare at your stats, very high heart rate for sleeping, back when wearing my fitbit it thought I kept being dead at times because it sucks at recording <60bpm.
Guessing you're still suffering from fitness problems and fatigue? Normal sleeping heart rate should be 50-70 usually in deep sleep, your heart rate while sleeping should dip down and then come back up. On average I have a high heart rate, I have high 70's/low 80's norm, when I go to sleep it started trending down and around 1/3 of the way through would drop below 60, past that point the watch was useless, then usually about two hours before waking up would start trending back up, hit around 65-70 before waking up.
Stopped wearing a watch to sleep when I woke up a few times due to it blocking blood flow if you move around in sleep and it rides up, this was still fitbit, so about 1.5 years ago, I've gotten fitter since then, but it's more been my heart rate now averages 73bpm according to my watch (right now while typing I'm at 74, about time for me to go for a run in 10 min), used to be around 78. I like the bpm on the watch as helps me measure how hard I am pushing myself while exercising, if I'm trying to do burst training, doesn't really make sense to me for sleep, otherwise stats are largely irrelevant.
