I think it's not depend on demon slayer's rank like Tanjiro. He has abilities and skills adopt from his father and his experience and succeed from Sakonji Urokodaki's training. Higher rank than Tanjiro has only have more experience in battling with demons than him that's why they're high rank. Therefore, it depends on demon slayer's skills and abilities.
