Well, lower DPI means improved aiming accuracy, similar to higher tablet area size. Too high of a DPI will lower your aiming accuracy. Only reason you don't lower it too much is because of the extra movement you need to make, so you make a trade-off.
You should really just play around with the DPI a bit and see which you like, I'm sure this is more effective than any amount of equations. Osu isn't an fps or starcraft 2, so advice given by team liquid doesn't necessarily apply to osu.
