Formula
x = Ability Points = 10*MainSlots+3*SubSlots

A = % change due to Ink Saver (Main) = (0.99*x-(0.09*x)^2)/(200/3)

B = consumption per flick = [base consumption per flick]*(1-A)

C = consumption per second while rolling = [base consumption per second while rolling]*(1-A)

Rolling time after initial flick = (100-B)/C

Base consumption per flick:
 * Carbon Roller: 3.5
 * Splat Roller: 9
 * Dynamo Roller: 20
 * Inkbrush: 2
 * Octobrush: 3.2

Base consumption per second while rolling:
 * Carbon Roller, Splat Roller, Dynamo Roller: 6
 * Inkbrush: 8.1
