Then you're ignoring my last example. Konoha's hospital battle. Sasuke thought Naruto was stronger and Kakashi stated that Sasuke felt 'inferior'. But Sasuke was in denial and only stated in Naruto's face how 'weak' Naruto was.
Don't you remember?

PS: It seems you don't know about 'relativity'. Even if Sasuke knows his own strength, he doesn't know his opponent strength. So stop reducing the analysis of what Sasuke knew about himself, because he didn't know about his opponent.
If you fight against me with your hands and you think you're stronger than me without knowing my own strength but only yours, and you state that I'm weak without knowing that I am a master in martial arts, who is bluffing? Yes, you, bluffing is not about ignorance about yourself only but about ignorance about yourself and your context.
