The unit
Why it is not priced per debate
A debate has no single price. What it costs depends on who is arguing it
and how hard they are made to think: two cheap models over three rounds,
and a frontier bench at high effort with a judge reading the whole
transcript, are not the same purchase — they are orders of magnitude
apart. A flat per-debate fee would either overcharge the first or
underwrite the second, and both are dishonest in the same way.
So an account is denominated in units. A unit is a fixed
quantity of work; each turn draws down as many as its model and its effort
actually cost. Cheap benches go a long way. Expensive ones do not, and the
chamber says so.
Nothing is spent before you agree to it. The roster prices every chair
while you are still choosing it — what one turn costs for a debater, and
what it costs for the judge — so the bill for a debate is on screen
before the motion is put, not after the ruling comes in.
