# The protocols behind the core matrix

Protocols

Each protocol fixes who was tested, how the data were split, which electrodes and window a method saw, what it was allowed to learn, and what guessing would score. A score is comparable only with other scores under the same protocol: there is no overall ranking.

A blank cell in the matrix is a protocol a method was not run on — not a failure. Chance level differs by protocol, so read each score against its own.
