Does anyone know how isseis boosted gear abilities work in BB. Ever since issei achieved BB I could never wrap my head around how the BG's abilities work(mainly the boost ability and how long that boosted power can be maintained). From my perspective valis DD sacred gear can keep power divided for a long time while in BB, but issei can only maintain his boosted power while in BB for a few seconds.

It's stumped me ever since LN 6 but I could never understand it, does anyone know how it works.
