SmoothDamp won't reach its target

I've been bashing my head for a while on this. Here's what I've managed to rule out:

-The CoRoutine is called only once.

-The while loop is constant, yet doesn't crash.

-The "percentage" float jitters around 0.2F

Here's the code:

 IEnumerator MoveTo(Vector3 endPosition) 
 {
     
     Vector3 startPosition = transform.position;
     Vector3 currentPosition = startPosition;
     
     float smoothTime = timer;
     float vel = 0.0F;
     float percentage = 0;

// yield return new WaitForSeconds(delay);

     while (percentage < 1)
     {
         percentage = Mathf.SmoothDamp(0F, 1F, ref vel, smoothTime);
         print (Time.time);
         currentPosition = Vector3.Lerp (startPosition, endPosition, percentage);
         transform.position = currentPosition;
         yield return 0;
     }
     
 }
