How to decrease the sensitivity of Iscroll5?

Question

I’m using Plguin Iscroll to scroll through to show a list on an IOS device.

I’ve been looking at the site where I downloaded the plugin (here), but found no information about decreasing/increasing scroll sensitivity.

Is there any instruction that does?

UPDATE

Inicialização do IScroll

        var wrapper = document.getElementById('treelist');
        myScroll = new IScroll(wrapper, {
            scrollX : false,
            scrollY : true,
            scrollbars : false,
            interactiveScrollbars : true,
            mouseWheel : true,
            hScrollbar : false,
            vScrollbar : true,
            useTransition : false,
            snap : 'li',
            tap: true,
            click: true,
            mouseWheelSpeed: 1,

            indicators : {
                el : '#scroller',
                fade : false,
                ignoreBoundaries : false,
                interactive : false,
                listenX : false,
                listenY : true,
                resize : false,
                shrink : false,
                speedRatioX : 0,
                speedRatioY : 0,
                checkDOMChanges: true,
            },

        });

In the same site there is the part of advanced commands that can be seen here: http://iscrolljs.com/#Advanced-options

I believe what you seek is:

options.mouseWheelSpeed
Modifica a velocidade do scroll do mouse.
Valor padrão: 20

If you want to change the acceleration/stop time of the movement is with the options.deceleration.
