Calculating total documents in Sanity usage using GROQ queries

Hey hey!
Can I ask how “total documents” is calculated in Sanity usage?
I’m asking because I’m trying to replicate that number using a GROQ query, to keep track of our documents.

I end up with either too many, or too few, depending on how I’m counting.
For example, do total documents count across datasets?

count(*[])

would count all documents in a dataset. This, however, would count all system documents and assets. Those aren’t counted toward your quota. I think something along the lines of

count(*[_type in $types])

where

$types

is an array of the document types you’ve defined in your schema should do it.

Thank you!
