El Profesor wants the number substantiated and El Crítico does not care about the number at all, because his objection survives whatever it turns out to be.
Reasoning and trade-offs · AI analysis
El Profesor scores it moderately and asks the obvious question about a self-reported saving with no method attached. El Crítico scores reliability lower and asks a different one: what happens when the thing dropped from the current turn was the constraint that mattered. His question does not depend on the answer to El Profesor's.
El Crítico wins, because a saving is only a saving if the output is still correct, and nothing in the row demonstrates that. El Amigo's enthusiasm for long sessions is premature. Trial only, and the exit criterion is a long task where you can verify the early requirements survived.
