File:Sprinkler Ink Saver N-ZAP '89 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)

ΔISS = Change due to Ink Saver Sub = (0.99 &times; A &minus; (0.09 &times; A)2 ) / (600 / 7)

CSUB = Ink consumption of Sprinkler = 80 &times; (1 &minus; ΔISS)

CMAIN = Ink consumption of N-ZAP = 0.8 &times; (1 &minus; ΔISM)

Number of shots after deploying Sprinkler = (100 &minus; CSUB) / CMAIN
