Some questions about Zenuriks "Systemic Override" passive

[Xanawolf]

Hey everyone, So before i grind a bunch of focus to get this passive id like some answer to a few questions i have about the passive itself.

1, At the lowest rank this passive gives 20% efficiency for 15 seconds, What is this at the max rank?

2, Is it possible to go past the 175% efficiency cap with this ability? 

3, So if i were to use my 5 to activate this passive and then use a channelled ability (Examples; Valkyr's Hysteria, Titania's Razorwing, Chroma's Effigy) Would the extra efficiency stay if i were to keep that ability active past the 15 seconds the passive is active?

Thanks for the help in advance. :) 

EDIT: 1 last quick question for Zenurik users, Besides from the energy regen what other talents did you choose?

I unlocked it to finish the focus tree, but don't have it active.  It's a waste that increases Focus charge time for so little gain.
