Multiple Mathf.SmoothStep on a single variable

I have a camera in my scene that moves to the side like in a side scrolling game. I have the camera gradually pick up speed over the course of 94 seconds, then after those 94 seconds, i want the camera speed to suddenly increase over a short period of time.However, no matter what i do, i cant seem to increase the value of the camera speed past the “maxSpeed” in the first Mathf.SmoothStep. See anything wrong with my code?
EDIT: The Speed now changes with the changed code, but it changes instantly no matter how long BoostAccelerationTime is, how do i make it change over time?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraMovement : MonoBehaviour {

    public float CameraSpeed;
    public float maxSpeed = 9f;
    public float accelerationTime = 94;
    private float minSpeed;
    private float time;
    private float minSpeed2;
    public float Boost = 10f;
    public float BoostAccelerationTime;
    

	void Start () {
        minSpeed = CameraSpeed;
        time = 0;
        minSpeed2 = 9;
	}
	
	// Update is called once per frame
	void Update () {
        time += Time.deltaTime;
        if (time < accelerationTime)
        {
            CameraSpeed = Mathf.SmoothStep(minSpeed, maxSpeed, time / accelerationTime);
        }
        
      
            if (time >= accelerationTime + 1)
            {
                 CameraSpeed=Mathf.SmoothStep(minSpeed2,minSpeed2 + Boost,time/BoostAccelerationTime);
            }

 transform.position += transform.right * CameraSpeed * Time.deltaTime;
        
        
    }
}

change the == of the seconf if to >=
