Original research

What sixteen platforms look like from the inside.

Reading every major competition platform once a day produces a second dataset alongside the listings: a record of how the platforms themselves behave. How late they publish. How often they answer. What they quietly stop returning. None of that is published anywhere else, so it is published here, with the method stated and the numbers recomputed rather than maintained.

Using any of this?

Everything here is free to quote with a link back. The numbers move as the archive grows, so cite the page rather than copying a figure, and if you need the underlying rows the listings are available as an open API. Journalists and researchers wanting a cut we do not publish can ask.
