Readiness score is wrong

[Specky]

See screen grab. According to the readiness scores, I didn't sleep much for two days straight.

But I had sleep scores of 90 and 84 respectively and more than 7h both nights, so this is inconsistent. I feel fine and I'm pretty sure I slept quite well.

The readiness score is wrong.

It appears to use the last 7 days of sleep. Not sure if that is your specific issue, however.

[Specky]

Thanks, but I don't see how this can be the issue. The last seven days' average is about 7h 30m, with an average sleep score of 87. Besides, earlier in the week when the average sleep durstion and score were lower, the readiness score was fine. In the four days after the one short sleep of 5h 51m, sleep score 88, I had higher readiness scores of 97, 29, 53 and 63. Given the other factors these look about right. But the last three days have had readiness scores of 19, 10 and 5, with the reason stated as "You haven't been sleeping much."

I'm not convinced 7h 30m average counts as "not much".

In settings > Activity>Sleep - what is your sleep goal?

[Specky]

The goal for time asleep is 7h 15m

@Specky it was a long shot. I havent asked the obvious, you have turned your device off and on again?. Power off, not reset.

[Specky]

Phone, yes. Watch, no, because it doesn't have a power off button.

Is this feature working for anybody? Because it smells like a bug in the app to me.

Basically it is broken for me now. Today, it is right for the score to be low, but the reason is the activity, not the sleep, which was 9h 8m last night and averages 7h 48m over the last seven days.

I contacted support, who had me reset the watch, then unlink and relink it. Nope, no change.

Since you asked, I know that this works for at least one person in my standard work week hustle group, and she loves it.

After a week of wrong 'recent sleep' indications, it now appears to have gone back to normal. I think it was wrongly processing one night's sleep, although there is nothing obvious about that night to trigger these issues. There is just one thing special about it: it's the only night with an 'Excellent' sleep rating since I started using the Readiness Score. So, dunno, but it has now fixed itself.

@Specky , out of curiosity. exactly one week? The reason I am asking is Sense has a "7 days memory". I do not know neither how, nor why, maybe one night severe misreading affects the score for the next week?

[Specky]

Actually no, the readiness scores had a wrong interpretation of sleep for five days. Perversely, the score plummeted after a sleep score of 90, stayed wrong for another four days with sleep scores 81-86, before returning to normal.

@Specky I have never had a sleep score of 90, mine is normally between 70-80, but I get bot low and high readiness scores. For me it seems how much effort I put into my running sessions that determine most of my readiness scores. It makes sense,if it varies from user to user since we all live diffeerent lives with different activity levels?

[Specky]

Yeah, I've only ever had two! For me, the difference between 85 and 90 seems to be: being tired before going to bed. I mean, obvious innit? But true. The difference between 75 and 85 was a whole raft of things including consistent bedtime and pre-sleep routine, cool room, clear airways & filtered air, no caffeine after 12pm and no alcohol, no food after 7.30pm, and much else. Took me a while to get there. The barrier I'm stuck at now seems to be an artefact of Fitbit's algorithms: to get any higher, I have to raise my (daytime) resting heart rate. At this point I'm just accepting the score I've got because I don't think lifting my daytime heart rate is sensible.

[charleskn]

@Specky I am curiously confused by your comment that you "don't think lifting my daytime heart rate is sensible." Your statement would lead me to believe that you have some issue which would make exercise impracticable. If that is the case, then I would wonder about the question here about the readiness score. Yes, we'd all like our tech to work as advertised. I am also pretty sure that, sometimes, I ignore some of the issues with the fitbit software/devices

[Specky]

Sorry, I wasn't clear. Fitbit's measure of my resting heart rate generally varies between around 49 and 53. The low value means that, when I sleep, I lose a few points because my sleeping heart rate occasionally rises above it. To get the sleep points I would have to raise my resting heart rate. Not even sure how I'd do that. Taking up alcohol and tobacco, maybe? I have no idea. But I don't think it would be helpful. 😉
