get value of tween before it happens

I have a few moveTos which I am running with quadratic easing, moving something to a targetPositition.

I really need to know at which point in time the object will be at a certain position, or for that matter, if it shall cross a certain position, that is predict it’s trajectory.

Is it possible to get this information from iTween? or has anyone got a clever hack around?

check gameObject.transform.position in Update()
