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

B = % change due to Middle Ink Saver Main = (0.99 &times; A &minus; (0.09 &times; A)2 ) / (200 / 3)

B = % change due to High Ink Saver Main = (0.99 &times; A &minus; (0.09 &times; A)2 ) / 60

C = Ink consumption = [base consumption] &times; (1 &minus; B)

Full charge count = 100 / C. Round down to a whole number.
