Yes, there has always been the possible interpretation that when Mitchell says "In Lieutenant Kirk's class, you either think or sink", he isn't talking about Kirk the Instructor, but Kirk the Annoyingly Perfect Classmate Who Sets Impossible Standards...
It sorta depends. There's that PSI chart stating that Mitchell made Lieutenant Commander at age 23 already; he could be that much younger than Kirk, then, although there's no particular reason to think that he's still 23 at the time of the episode. Did Kirk make Lieutenant Commander at 23?
Well, we don't know such elementary facts as when he entered the Academy or when he graduated, but in "Court Martial" we do hear him describe Finney as fellow Academy student and then go on to state that "seven years later" he himself still only held Ensign rank... And he was still Lieutenant in the "Obsession" backstory which does get dated to eleven years before the episode. But if he got promoted right after that very adventure, he'd match Mitchell's career development.
