I think that recurring and supporting are in two different categories that can overlap. "Recurring" simply means, well, recurring. They appear more than once. So any non-main character who appears more than once is recurring.

"Supporting" means that they have had anything more than a minimal role to the plot at some point.

So, Unnamed pointed nosed woman would be recurring but not supporting, Gabe Bensen would be supporting but not recurring, Pacifica Northwest would be both, and Unnamed miner would not be either.
