Every roll lands inside the range real players use, so you never get a sensitivity that's unplayably fast or slow. Pick a game, set your DPI, and see how far you'd sweep to turn a full 360°.

Press roll to get your first one.
The bar shows how much mousepad one full 360° turn eats up.
The same 360° distance in other games
Sensitivities are generated from distance, not from the raw number: the roller picks a cm/360° inside the usable band, then converts it with each game's turn rate — cm = 914.4 ÷ (yaw × sens × DPI) — and rounds to a value the game accepts. Windows pointer speed should sit at 6/11 with enhance pointer precision off, or the conversion won't hold.
