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

Formula
$$A = Ability Points = 10 * Mains + 3 * Subs$$

Δ$$_{ISM} = Change due to Ink Saver Main = (0.99 * A - (0.09 * A)^2 ) / (200 / 3)$$

Δ$$_{IRU} = Change due to Ink Recovery Up = (0.99 * A - (0.09 * A)^2 ) / 67$$

$$C = Ink Consumption = 0.3 * (1 - $$Δ$$_{ISM})$$

$$S = Shots Per Tank = 1 / C$$

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

$$F_1 = Number of frames in the time being measured = 3600$$

$$F_2 = Charging and Firing Frames = 100$$

$$F_3 = Ink Submerging Animation Frames = 28$$

$$F_4 = Ink Recovery Frames = 180 * (1 - $$Δ$$_{IRU} )$$

$$Shots Per Minute = F_1 / (F_2 + F_3 / S + C * F_4)$$

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