Stingray Special – pickup height

I bet this has been asked many many times, but couldn’t find a topic regarding Stingray Special.
I have this beautiful 2020 Stingray Special bass which I love. I have been fiddling with pickup height but haven’t been able to find the sweet spot with it.
What are the factory specs for single pickup version of Stingray special. Is it measured last string depressed and from polepieces or plastic cover.
My bass has flush polepieces so does it change anything?
