I am no expert on this, I simply practised with different builds of my formatting until I got the collection as I wanted it.
In my example of formatting, if one level of / is removed I would get a collection called Shelf, but no further level of breakdown. So, my format tells the Tolino to create an internal folder called Shelf, then a Collection called {tag} and organise my books within those Collection.
Your best option is probably to try it yourself.
The author sort I referred to is using Tolino's in built sort option.
By way of correction, I note I gave the wrong metadata plugboard format - the format I use to ensure books within a series are listed in order on my Tolino is {series_index:0>2s|[|] }{series:|| } {title}.
