As far as i know and based on my experience, Scaling Buffs such as Minato Jonin's Scaling from Chase is not affected by Han or Madara Five Kage Conference's Skill .. Same with buffs without Round-Limitation like Madara Founder and Hashirama Skillbroken .. While those with Round-Limit like Iruka's skill (5 rounds) and barriers, they are affected ..

No worries, glad to that i helped you
