Mathf.Clamp issues

Hi there, so i have a script for camera movement/control and it was giving me issues related to a clamp it was going beyond the boundaries and returning to the position instead of just clamp, so i decided to do a new script more simple, and it's doing the same.

Previous problem: The other script which is more advanced and better done have those problems too.

Problem: If you use this script in a camera and move fast the mouse to down or up it will go beyond the clamp and then return to the clamp.

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
  
 public class MouseLook2 : MonoBehaviour{
 
     Vector2 mouseDelta;
     Vector3 absolutePosition;
     Vector3 finalRotation;
     Vector3 smoothedPosition;
 
 
     public Vector2 yLimit = new Vector2(-75,150);
     public Vector2 sensitivity = new Vector2(2, 2);
     public GameObject characterBody;
 
     public void LateUpdate(){
 
     mouseDelta = new Vector2 (Input.GetAxisRaw ("Mouse X"), Input.GetAxisRaw ("Mouse Y"));
         
 
         //Add inverted mouse delta value of Y (If we want inverted view just delete the negative sign)
         absolutePosition.x = -mouseDelta.y;
         //Add Mouse delta value of X
         absolutePosition.y = mouseDelta.x;
 
         finalRotation = absolutePosition;
         finalRotation = new Vector3(Mathf.Clamp(finalRotation.x,-yLimit.y,-yLimit.x),0,0);
         transform.localEulerAngles += finalRotation;
 
     }
 
 
 }

Thanks in advanced.
