I recently created a pocket query (from a bookmark list) and checked one day: Saturday (today).
Additionally I checked: send it once a week.
And: Yes, I clicked only ONCE!
After a minute I got 5 mails with the same pocket query.
The PQ view also shows that this query has been created 5 times, the 6th one still has status "never" because my daily limit of 5 PQs is now gone.
I don't know if it's related, but the PQ, built from a bookmark list, contains 6 caches (not 1000 as shown in the screenshot).
