British Parliamentary is the world’s most-debated format: four teams, eight speakers, seven minutes each. This timer paces a single speech with its protected structure — a protected opening minute with no Points of Information, five minutes of open floor where POIs may be offered, and a protected closing minute — ringing the bell at each knock and at time.
Those signals are the whole rhythm of a BP speech: the knock at one minute tells the speaker the floor is open, the knock at six warns them to wrap, the bell at seven ends it. School circuits often run five-minute speeches with the same protected first and last minute — open the preset in the editor and shorten the open floor to switch. Start a fresh run for each speaker around the table.
