Percentile among shows you could realistically get on. Not a download count.
Check whether they charge. Some shows sell guest slots rather than booking them, and rates in some fields run to thousands. Nothing in a podcast feed reliably says so, so we do not claim either way. Ask before you write the pitch.
Worth a pitch. This show publishes its own contact, sits outside the national chart, is independently published, and its recent episodes show it books guests.
