No.

So Klaus's leader skill(I hope you are talking about the leader skill) reduces the amount of BC required for BB/SBB. When having him as lead,when you start a battle or after you use your BB/SBB, you'll have some BC in your BB Gauge.The BB Efficacy is how much BC fills up when you get it.(I don't know how to explain it cleary sorry). His Leader Skill boost BC effifancy,that means when you get 1 BC, the BB Gauge will fill up like its more than 1 BC
