I have stupid question to ask you guys.

How exactly does Issei's Boosted Gear boost his power? I know that it's all just Ddraig's ability and Issei can use it because he has his sacred gear. I'm just asking what rule does the boosing work by.

Is it

(Base Issei) x (# of "BOOST"s)? example: Issei uses BOOST three times making him 3 times stronger.

or

(Base Issei)^n (n = # of "BOOST"s)? example: Issei uses BOOST three times making him 8 times stronger.

If this has already been explained in the Light Novels, please tell me where it is so I can read it. Thank you, and I'm sorry for the stupid question.
