The Institution · Once a fortnight
Seven parts, forty-five to sixty minutes, inside a window of three days that opens every fourteen. Standing Δ moves here and nowhere else. A missed window pins the figure at its last assessed value until the next opens.
Reading the window.
The last quarter of the sitting is a stress test of the first three. This is deliberate. A faculty that holds for ten minutes and gives way at forty has not been measured — it has been sampled. Endurance is built into the Standing Δ because it is the faculty most affected by what the Fellow does with the rest of their day.
Meanwhile the Preliminary is open, and it is sixteen rounds against the same four faculties. It is an entrance examination, not a Diagnostic: it will place you, and it will not move a Standing Δ.
