[1Zpresso X-Ultra] is this much retention within tolerance?

1Zpresso X-Ultra is retaining about 0.3g of ground coffee. Is this just par for the course with these units? Or am I doing something wrong?

(For the content minimum): Getting 36g out in 28s. Bambino Plus. Tastes great. Just annoyed with how messy the grinder is.
