Diminising return implies reduced effectiveness after each stack e.g. stacking 3x 200% damage increase will reduce the effectiveness of the latter two by this formula

1x=200%+100%base = 300% or 300%/100% = 200% increase from the previous

2x=500% or 500%/300%= 66.67% increase from the previous

3x=700% or 700%/500%= 40% increase from the previous

This "efficiency" one is the opposite but there's a cap. Say, 3x 25% stack

1x=1-0.25 = 0.75 or 1/0.75 = ability to spam 33% more times before it's empty from the previous

2x=0.5 or 0.75/0.5= ability to spam 50% more times before it's empty from the previous

3x=0.25 or 0.5/0.25= ability to spam 100% more times before it's empty from the previous

Though it has a cap at 90% so let's include it

90% efficiency compared to 75% = 0.25/0.1= 150% more to spam than 75% eff.

As you can see, efficiency bonus effectiveness just keep growing more and more with each %.
