Yes. Like in a plane with an altimeter telling the plane is 1 miles
above the sea, when the plane actually *is* 1 miles above the sea
(with respect to its most probable relative computation history).

"Correctly implemented" means---assuming comp and thus assuming the
existence of the substitution level---that the doctor has luckily
implemented the "Napoleon's software" at that correct level (or below).
