If MouseWheelVariation is MouseWheelVariations.Absolute, MouseWheelValue will contains the absolute value to add or substract from current value.

If MouseWheelVariation is MouseWheelVariations.Percentage, MouseWheelValue will contains the percentage of variation from current value (default MouseWheelVariations.Percentage).

MouseWheelZoomPosition

MouseWheelXXXXX properties allow application to customize the mouse wheel behavior.

If MouseWheelAction is Zoom, MouseWheelZoomPosition specifies where the zoom act.

The default is the center of the control (MouseWheelZoomPositions.Center), otherwise (MouseWheelZoomPositions.Mouse) zoom at the mouse position.
