File:Ink Recovery Up vs Ink Saver Main E-liter 3K Chart.png

Formula
A = Ability Points = 10 &times; Mains + 3 &times; Subs

ΔISM = Change due to Ink Saver Main = (0.99 &times; A &minus; (0.09 &times; A)2 ) / (200 / 3)

ΔIRU = Change due to Ink Recovery Up = (0.99 &times; A &minus; (0.09 &times; A)2 ) / 67

C = Ink Consumption = 0.3 &times; (1 &minus; ΔISM)

S = Shots Per Tank = 1 / C

Round S down to a whole number, because there is never a fraction of a shot.

F1 = Number of frames in the time being measured = 3600

F2 = Charging and Firing Frames = 100

F3 = Ink Submerging Animation Frames = 28

F4 = Ink Recovery Frames = 180 &times; (1 &minus; ΔIRU)

Shots Per Minute = F1 / (F2 + F3 / S + C &times; F4)

Round final result down to a whole number, because there is never a fraction of a shot.
