scrollToCenter is bumpy

(version 2.3.0)

Timeline._Band.prototype.scrollToCenter = function(date, f) {
var pixelOffset = this._ether.dateToPixelOffset(date);
    if (pixelOffset < -this._viewLength / 2) {
        this.setCenterVisibleDate(this.pixelOffsetToDate(pixelOffset + this._viewLength));
    } else if (pixelOffset > 3 * this._viewLength / 2) {
        this.setCenterVisibleDate(this.pixelOffsetToDate(pixelOffset - this._viewLength));
    }
this._autoScroll(Math.round(this._viewLength / 2 - 
this._ether.dateToPixelOffset(date)), f);
};

I don't really understand the point behind the two conditions and the 
setCenterVisible, it makes the scrollToCenter() function bumpy
