Basically out of hundreds of screenshots. Every location consists out of 20 4k (3840x2160) images that I merge together with PTGui.

After that I use krpano to make the 360° tour and link the hotspots together.

That depends on the length and the features of the track. Boiled down to one location you can say it takes me around 20 minutes.
As of 2023 S4 there are 10.798 locations. Yes, that is around 150 full 24h days of work.

It already takes me 12 minutes for one location to get the images and double the resolution takes four times the time I don't see that in the near future happening.

Thanks but at the moment I don't really need help.

But subscribing, even the Oval Only Subscription contributes to covering the costs

Great! Please go to the location, right-click (or press and hold, when on mobile) and the click on "Report Bug"

Alternative you can find me on a lot of Discords, just DM me. If that is not an option you can always send me an email.
