He's levitated himself, another person, as well as an airspeeder simultaneously shortly after RotJ. He also halted a freighter mid-crash, though I've heard that there are more details to how he accomplished this. He also has a statement saying he's as powerful as Vader. Also, as a Telepath, he's probed the minds of enemy ship pilots and forced them to fire on their allies from a great distance, which in itself is a great TP showing. He's also expanded his senses to the size of an entire asteroid field, detecting everything within its borders.Him supporting an At-St for a couple seconds is hardly the pinnacle of his force achievements.
Yes, Luke safely landed himself, his airspeeder and Isolder like feathers in Courtship of Princess Leia book, which is an unparalleled feat. In the same book he blocked lightning of a powerful witch and chopped her head off. However, in the same book he nearly died from Gedzerion's Force blast and his thought was something like this is how it would be, if Vader used full Force on him. And a year later he was pretty much helpless against C'baot in final confrontation.
It shows that he already more or less reached his Force potential, however, he still lacked experience of effectively utilizing this potential during combat.
If it was sabers only gauntlet, I would agree that he can reach 9 but in all out he might lose even at 1.
