Question about gcpe_currently_queued_tasks_count nevering draining to zero

Hi,
Is it normal that the gcpe_currently_queued_tasks_count never drains to zero? Its always hovering at around 500ish. Overall I think the exporter is working as expected but was curious if this is a problem.
Here is my config:
