animate() doubles duration on first loop

[LanFeusT23]

When using the duplicated option, the animate function will double the duration of the first loop.

on line 255:

if (o.duplicated) {
    //When duplicated, the first loop will be scroll longer so double the duration
    if (loopCount === 1) {
        o._originalDuration = o.duration;
        if (verticalDir) {
            o.duration = o.direction == 'up' ? o.duration + (containerHeight / ((elHeight) / o.duration)) : o.duration * 2;
        } else {
            o.duration = o.direction == 'left' ? o.duration + (containerWidth / ((elWidth) / o.duration)) : o.duration * 2;
        }
        //Adjust the css3 animation as well
        if (animationCss3Str) {
            animationCss3Str = animationName + ' ' + o.duration / 1000 + 's ' + o.delayBeforeStart / 1000 + 's ' + o.css3easing;
        }
        loopCount++;
    }
    //On 2nd loop things back to normal, normal duration for the rest of animations
    else if (loopCount === 2) {
        o.duration = o._originalDuration;
        //Adjust the css3 animation as well
        if (animationCss3Str) {
            animationName = animationName + '0';
            keyframeString = $.trim(keyframeString) + '0 ';
            animationCss3Str = animationName + ' ' + o.duration / 1000 + 's 0s infinite ' + o.css3easing;
        }
        loopCount++;
    }
}

What is the reason behind that? Could we have an option for this instead?

Thanks,

This is very hard to explain but it work as show in the demo? Which part of these lines you don't understand?
