Player movement with lerp is jerky.

Hey!I have a question! I've got this piece of code:

         ...
         if (TargetChanged(Target, TarLastPos))
         {
             if(isLerping)
             {
                 StopCoroutine("LerpPlayer");
             }
             StartCoroutine(LerpPlayer(0.5f));
         }
     }
     //FUNCTIONS
     bool TargetChanged(Transform target, Vector3 lastPos)
     {
         if (
             //Target moved a tad
             Mathf.Abs(target.position.x - lastPos.x) > 0.01f ||
             Mathf.Abs(target.position.y - lastPos.y) > 0.01f ||
             Mathf.Abs(target.position.z - lastPos.z) > 0.01f
             )
         {
             return true;
         }
         else
         {
             return false;
         }
     }
     //Move player so it is in fron of camera
 
     IEnumerator LerpPlayer(float duration)
     {
         isLerping = true;
         Vector3 StartingPos = Player.transform.position;
         float StartTime = Time.time;
         float MovementPercent = 0f;
         while (MovementPercent < 1)
         {
             MovementPercent = (Time.time - StartTime) / duration;
             this.transform.position = Vector3.Lerp(StartingPos, Target.position, MovementPercent);
             yield return null;
         }
         isLerping = false;
         this.transform.position = Target.position;
     }

What it should do:It is meant to make the player's position get lerped to where the camera is pointing(indicated by the Vector3 Target) and because it is a Lerp, I need it to be in a IEnumerator,but that also means to not cause imense lag i set up a function to detect if the camera(Target) changed and so it stops the coroutine and start's it again, this time having the new Vectors.

What it does: It works...sort of. The player is "jolty" indicated in the gif, and I am not quite sure why, it should be smooth..

P.S. I couldn't find any question/answer that solved my problem yet, but I might have missed the answer i was looking for.
