Where this data comes from. Shows are discovered from Apple’s public index and refreshed
three times a day. Contacts are read from each show’s own RSS feed, where it publishes an owner
address. Never bought from a contact database, never guessed from a name pattern, never probed.
Reach is a percentile among the shows you could realistically get on, derived from a 0–100
composite of chart history, longevity, publishing activity and cadence: all free, published
signals. It is not a download figure. Nobody outside a show can see its downloads, and any
tool that claims otherwise is estimating. Where a show publishes no contact we say so and link to
its own page.
