I have a Huawei GT3 Pro Watch, which tracks my sleep.

Almost every single night, I get dinged because my deep sleep continuity is always <70.

The only exception, is when I get very little sleep, ie Last Night when I got a total of 3 hours 59 minutes and my DSC was 81!

It seems like the longer I sleep the worse it gets, but I very rarely sleep more than 7 hours, perhaps, if I am lucky, twice or three times a month, usually averaging between 6-7 hours.

It's suspected I have sleep apnea, though I am still, 6 months later, waiting for the results of my sleep study (They estimate Sept)!.

Anyone got any insight into how they measure this, and if it's something I should actually address or this is my 'normal'?

I would be a bit careful about the accuracy of sleep stage measurements on wearables. If you search for The Quantified Scientist on YouTube then you will find some very interesting controlled tests showing that some devices perform well but none of them are perfect.

For what it's worth my Apple Watch shows my deep sleep being minimal most nights, but I feel fine as long as I get at least 8 hours. 8.5 hours is ideal, but too much more than that messes up my body clock and affects my sleep the following night. Anything less than 7.5 hours feels terrible.

If you are sleeping less than 7 hours and have evidence of minimal deep sleep then I would be looking into it further.

Was the sleep study via the public system? That's a shocker.

My views (except when I am looking out their windows) are not those of my employer.

Yup, frustrating. They said it would be a long time if there wasn't significant items to be remediated but I thought that might add 3 months. :)

As said above, the sleep stages on wearables are an estimate at best so be careful how much weight you place on them.

That said I always thought that I was deficient in deep sleep according to my Garmin watch. On a typical 7hr30min sleep I would get less than 45min of deep sleep. But when I saw other people's stats I saw that most people only got 40-70min of deep sleep a night.

For me, the volume is more important than any stages. I can function on 7 to 7:30 hrs, I much better on 8+ hours and I'm feeling on top of the world on 8:30hrs.

Interesting. Last night I got a DSC of 93, by FAR the highest I've ever had (in about 2 years or more!). I simply don't get it.
