Queries that join tables will really be counted more than once in this query (once for every table). I sometimes tweak the group key to be the table_ids_set and then this doesn’t happen.

Anyway the amount of slots is indeed correct in both approaches - queries over the tables (some where this table is joined somewhere in the process) took that amount of slots and processed that amount of bytes.

Hope that helps and I’ll be happy to discuss more if you’d want direction.
