Hi Elia, glad to have you on this site. There can be value in determining the real-world versus theoretical knowledge of those you listen to, and I think it is safe to say that in Paul's case it is many years of hands-on
experience combined with the theory of why the practice works. While I am not remotely qualified to answer that question, there are a couple of quick things I can point you to that show he has, at least, some practical experience:
When I met Paul (many years ago), he was temporarily in an urban environment. It was easy to find his house - it was the one with the raised beds out the front. You can see some of his raised beds
here. If you would like a little more specificity, then the urban ones are the ones
here (and they produced wonderful vegetables).
Prior to that, I know Paul used to have a farm. There are some
pictures of the chickens he used to have, that were completely free to roam anywhere and everywhere.
There are many other things that I know Paul has had hands-on experience with, before, during, and after those two small examples. I suspect the best thing to do though, is to look at what he has written / the podcasts he has made, and see if it makes sense.
