Note that q-nodes mean the number of position that are evaluated.

It means that at depth 1 from the opening position all the nodes except the root
position are qnodes so you have 20 qnodes.

I guess that you do not use this definition for calculating qnodes.
I also do not use it and for me qnodes are additional nodes that I search
because of qsearch.
