Toyota listed the 1985 Celica Supra in more than one configuration, and the trim a car was built as is what decides which set of published values applies to it. This service and repair manual is written to the 1985 model year, so the figures you work to are the ones Toyota issued for this car rather than numbers carried over from an adjacent year.

Safety and service record. NHTSA holds no recall campaigns for the 1985 Celica Supra, and no owner complaints and no technical service bulletins are logged against it either. There is no published fault pattern to use as a shortcut, so diagnosis on this car starts from Toyota's own test values and procedures rather than from a known-bad part.
Four decades on, that is what settles whether a reading is out of tolerance or simply old: the number Toyota published for a 1985 Celica Supra in your trim, not a figure borrowed from a later car.
