Proc chances are independent. They do not stack with each other.

People say Isterio is better for inflicting status ailments because that 10% and 15% chance is applied to all attacking units. He adds status infliction effects to units' attacks. Lance is on his own when inflicting status ailments if he has the SP skill enabled.

Also, this applies to any attack, whether it'd be normal attack, BB, SBB, etc.
