Thousand Autumns

How the Pulse Score works

For series, Pulse starts from the IMDb rating shrunk by vote count, then applies FORMAT CALIBRATION. Series score systematically higher than films on IMDb, so using the raw number would unfairly push a show like Thousand Autumns to the top of a film catalogue. Calibration maps the series distribution onto the film one; meaning 66 is COMPARABLE to a film with the same Pulse.

One more difference from films: Letterboxd does not track series, so series Pulse derives from a single source (IMDb) rather than two.
