standalone input module and sliders

I' making a menu with horizontal sliders that the user interacts with using controllers. I've noticed that the method of simply hooking up the standalone input manager with the axes of the controller works, except that for slider input, the slider only moves a tenth of it's total distance for every flick of the joystick which is not the precision I would like to achieve. It is pixel precision when dragging the slider with the mouse.

I would like to make a slider that changes its value smoothly and with better precision than this from joystick input. Preferably using the event system and preferably not too much of a hack since there are many sliders in the menus I am creating.

Thanks!
