Regarding  Issei's [Boosted Gear]. If all ready doubled, does his power double the already doubled power when he [Boost]s again or not? For example:

Three [Boost]s = Base power times four. Base * 4.

or is it:

Three [Boost]s = Base power times eight. Base * 2 ³(2^3).

I reread the question over and over again and it still doesn't look right, so I apologise in advance for any confusion.
