The passage around this formula
W is a documented constant, published on day one of a model’s release, identical no matter who asks. is a measured variable — specific to a task, a threshold, a benchmark design, and a date — and every result surveyed above shows it running well below W well before W is reached. The two quantities answer different questions, and only one of them is available the moment a model ships.
