Of course, we know that Beowulf's SDF has 36 SDs, which is well above that 5 SD average. If other actual SD users have fleets of similar size, that leaves plenty of the 600 SDFs without any SDs at all, but the total number of SDs owned by all SDFs combined would still reach the thousand mark.
If you're building SDs to really use then the minimum number to be effective, and form even the most abbreviated wall of battle, is 4. But even with 6 it would be impossible to keep 4 in nearly ready to operate status.
Most wet navy ships do well to keep 1/3rd deployed. Normally it's 1/3rd doing post cruise activities/minor maintenance/pre-cruise workup, 1/3rd in major maintenance and overhaul, 1/3rd deployed.
(Right now it appears out of 10 US CVNs, 3 are back in home port, 4 are in major maintenance/upgrade, and 3 are deployed)
Even if SDs need less maintenance and your SDF is hanging around the home system most of the time you're still likely going to need somewhere between 33%-50% "extra" SDs to be reasonable sure you've got your minimum number ready to go when needed.
So an SDF with a target of always having a 4 ship SD squadron ready would likely need between 6-8 active (non-reserve) SDs to achieve that. So I'd be really surprised if any SDF bothered to have less than that number. At that point you're better off operating a useful number of BCs for your money and manpower. (At least in my opinion )
The RMN had a practice of keeping <15% of it's wall in maintenance at any time. When it exceeded this during the first war pushes pre-Icarus, it caused long term availability issues.
We know the Havenites relied more on depot maintenance in the 1st war due to training issues, bubt how much was never stated. SLN BF never operate outside the SL Shell, so probably rarely deploy away from their base.
So in the Honorverse, ship uptime varies widely between navies.
