Thanks!
Make sure you join the group and post any questions.
I watched the Tiger doc in bed last night and Whoop auto detected sleep an hour early. Editing my sleep time from 11:08 to 12:03 reduced my recover from 75% to 51%.
My HRV goes from 85 to 67.
I thought it detected HRV when you woke up to determine your recovery. Or maybe the last 15 minutes or something.
Thatās happened to me a few times. My recovery and HRV always drop. HRV is measured in the last 5 minutes of your last deep sleep cycle.
Well then thatās just weird. Iām adjusting the start time. Not the wake up time. I wonder why that changes so much. I was still just lying there resting. I just wasnāt asleep at 11:08.
I had the opposite thing happen a week or so ago where I got up in the middle of the night to pee (old man vibes) and WHOOP decided I was up for the day at 3:15 AM. When I adjusted my sleep time, my Recovery went from somewhere in the 40ās to somewhere in the 70s and my HRV increased accordingly.
Which is ā¦ suspicious. I guess it was ignoring the data of my last deep sleep cycle as said above, then āsawā it but it is still a little flaky seeming to me.

This type of thing has happened to me enough that Iām overall suspicious of the data. Have had a whoop for about 9 months. Really informative and fun to learn about a few things, but I think it has run itās course with me.

They had a recent article talking about how your goals for HRV should be more on consistency rather than simply trying for a high number. Itās easy to nit-pick a single day, but might be missing the forest kinda thing or whatever.

Someone posted this recently on r/whoop. Pretty lengthy, but really good insight into HRV goals.

Iām fighting that same feeling.
Editing the start time of my actual sleep shouldnāt, it seems to me, have this effect.

shoot them an email. Sent them a few for different reasons. They can look over and explain what the algorithm saw.
Also, 4 hours of sleep cause the baby landing me at ā¦ 80% recovery? ā¦
Guess iām working out with coffee in hand.

I might ask them the very specific question about editing my initial sleep time and its effects.

Overall, I think itās a neat device but Iām not a committed enough everyday athlete to derive enough benefit out of it to justify the ongoing membership charges. I paid for the year and Iāll put it away in July.
Iām definitely leery of how things can change but it isnāt making me reconsider using it. Iām no athlete in any real respect, but I do feel like when I am in the green and can push it, thatās good information (which I donāt always use) and itās just a good indicator of how my body is doing. I have had days when Iām in the green but my legs are sore AF from a bike ride, so it doesnāt mean I have to go nuts that day, and days when maybe I didnāt sleep so well, but I can still knock out a good ride, etc.
Itās just one piece of data, and itās a good health tracker - I like it more than the Apple Watch which insisted on telling me how many times I stood up every day which was fairly useless.

Itās all about what you make of the data.
Itās super fun to play science experiment on yourself. Take some melatonin. Maybe a bit of the devils lettuce. See if/what affects recovery. And capitalize on that when you need it. ( big runs. Golf tournament. Etc)

This is exactly it. Iāve got a lot of really interesting insights on what appears to help me recover: consistent sleep/wake, hydrating, not boozing, eating well and Iāll take all those moving forward. It was a useful tool and a fun toy.
And @iacas curious what they say about changing the times.

I just sent the question in and will report back.
Like I said, I did the same āstuffā during that time. I was fairly sedentary. My eyes were just open. I thought if I said I slept less, my recovery might drop a little bit, but i was surprised my HRV changed.
Rest is rest. I could have been meditating for an hour.

Iāve had a suspicion for a while that Whoop struggles with a particular use case. Iāve noticed whenever I do a very high strain day, the next day it has me in the green with a high HRV and then the 2nd day is when it drops.
Yesterday I woke up with a 95% recovery and 163 HRV. Did a really hard peloton workout and followed it up later with a pretty decent run. Strain for the day was 15.8 and a legit 15.8 not this I wore my band on my wrist and played golf in a cart 15.8.
I did spend some time stretching yesterday, I ate and hydrated well and got 8 hours of sleep. So there is that.
But I woke up this morning to a 94% recovery and my HRV was 167! Recovery was lower cuz my resting HR went from 35 to 39. Today was a light day, I bet I have low yellows for recovery tomorrow.

Holy shit.
Also in response to my inquiry to Whoop.
I apologize for any misunderstanding here. When you manually edit your sleep on WHOOP, we re-process it and take into account the new time window that you provided. WHOOP measures HRV and RHR during the last 5 minutes of the last slow-wave sleep cycle to calculate your Recovery score, so changing this period can potentially change your HRV, RHR, and Recovery.
If a sleep is edited, whether by minutes or hours, the reprocessing of the whole sleep occurs and WHOOP processes sleep second by second. This ātellsā WHOOP that the first sleep was not correct and, so it believes the first place that RHR and HRV were taken was not correct either. Then the algorithm will skip over that first measurement point and completely pull from the next most accurate SWS portion of the night.
HRV is a highly sensitive metric and it will fluctuate throughout the day and night drastically based on the state of the autonomic nervous system. So, it is normal to see this change in the metrics.
I intend to follow up and ask about that ālast five minutesā and how that shouldnāt have changed to produce a different HRV number. I edited the start time of my sleep, not the end time.
Itās possible itās using the start as a bench mark time. So your time you edited out could have played a part in their algorithm.
Just spit balling. Iāve seen it do some odd stuff to mine but I chalk that up to being up in the middle of the night with the baby.
But reading that Reddit post, HRV sounds more like iron dispersion than anything. No point of hitting your 9i 200 yards to spray it all over. Seems like more tight dispersion is a better indication.
Exactly. Great analogy. Itās more about consistency, then trying to go for the highest number possible.
