Reading a radio diary without flattening the week
Monday kitchens and Sunday mornings are not interchangeable. Averaging them into a single listenership number is how a breakfast empire gets invented.
A radio diary that is summed into one weekly reach will hide the only hours a station still owns. We keep Monday-to-Thursday kitchens apart from Friday leakage and from Sunday religious hours that a Tbilisi-trained clock forgets on this coast.
Named bulletins need a second mark: on, and attended. A set left playing under conversation is not the same as a presenter who still has the room. Sales dislike the distinction. Editors need it before they move a journalist to 07:00 on the strength of a kitchen being switched on.
When we flatten a week for a board meeting, we say so on the plate. The unflattened tables stay in the bound report for anyone who has to live with the clock.
