Tweener and a large container

[LEFT]Hi![/LEFT]
[LEFT]I am working on a gallery:[/LEFT]
[LEFT]the slider rotates the container with the images using Tweener class and easeOutCubic transition.[/LEFT]
[LEFT]There are 45+ images around the center of the container[/LEFT]
[LEFT]

[/LEFT]
[LEFT]The movement is not smooth, especially when comparing to the way it would be with a small container.[/LEFT]
[LEFT]Also, and most important - A rough “snap” appears randomly in the end of the motion.[/LEFT]

Code:[/LEFT]
[LEFT][COLOR=black][FONT=Arial]perc = (100 / (rulerMaxX-rulerStartX)) * (ruler.x-rulerStartX);
finalRotation = minRotation + ((maxRotation)/100*perc);
Tweener.addTween(mc.inner, {rotation: finalRotation, time:0.3,transition:“easeOutQuad”});
