Frequency of maintenance windows in Android Doze Mode

Is there any documentation on how frequent are doze mode maintenance windows in Android? I have read different things but nothing official. Someone said its 1, 2, 4, 6 hrs and then maintenance window re-occurs every 6 hours but could not find it anywhere in android documentation.

It seems that we can do assumption only about duration of maintenance windows, rather than about frequency. As docs say, it's unstable value:

Over time, the system schedules maintenance windows less and less frequently, helping to reduce battery consumption in cases of longer-term inactivity when the device is not connected to a charger.

And what about duration of maintenance windows, it seems that they should be equal 10 minutes for jobs and network connectivity, and 10 seconds for alarms. From docs:

** If jobs restrictions are in force, the app is granted a window of ten minutes at the specified interval. At the end of the ten minutes, all jobs are postponed until the next window.

† If alarm restrictions are in force, all alarms will fire at the scheduled window, and run for a maximum of 10 seconds.

‡ If network access is restricted, the app is granted a window of 10 minutes to use the network at the specified interval.

P.S. There are also Doze-on-the-go, or Light Doze, since Android Nougat, and in that new mode the maintenance windows are more frequent than what we saw with Deep Doze (on plain Doze mode). P.P.S. It's possible also that OEMs are free to tweak the different timeout values.
