Add GameObject to List using Timer

Hey guys,

I've written a short script to add a gameobject (from an array of gameobjects) to a list of gameobjects (that will be used to spawn those gameobjects). The script works perfectly find, but I was wondering if any of you genius if this is good, I've added to many timers in one method and personally speaking, it doesn't look very good (from my point of view). Does anyone have any idea how to simplify this or an alternative way to achieve the same thing? I've recently gotten back into programming and my memory is a bit rusty.

Thank you all and hope this script may help someone in future! :)

 using UnityEngine;
 using System.Collections; //This allows the IComparable Interface
 using System.Collections.Generic;
 
 public class LevelController : MonoBehaviour 
 {
 
     // Array Stores All Platform Prefabs
     public GameObject[] Platforms;
 
     // List Stores Platforms To Be Spawned
     public List<GameObject> PlatformToSpawn;
 
     // List Containing Platforms Spawned
     public List<GameObject> PlatformSpawned;
 
     public int CurrentCount;
     public int NextCount = 5;
     
     // Use this for initialization
     void Start () 
     {
         // Execute Method to Add Platforms to Platform Spawn List
         StartCoroutine(AddPlatformTimer());
     }
 
     // Method to Add Platform to Platform Spawn List Based on Timer
     IEnumerator AddPlatformTimer()
     {
         // Execute Method to Add Platform To The List
         AddPlatformToList(); 
 
         yield return new WaitForSeconds(2);
 
         // Execute Method to Add Platform To The List
         AddPlatformToList();
         Debug.Log("1. Timer Finished Executing!");
 
         yield return new WaitForSeconds(2);
 
         // Execute Method to Add Platform To The List
         AddPlatformToList();
         Debug.Log("2. Timer Finished Executing!");
 
         yield return new WaitForSeconds(2);
 
         // Execute Method to Add Platform To The List
         AddPlatformToList();
         Debug.Log("3. Timer Finished Executing!");    
     }
 
     // Execute Method to Add Platform To List
     void AddPlatformToList()
     {
         // Increase Current Count and Add Platform to List
         for(int i = CurrentCount; CurrentCount < NextCount; i++)
         {
             // Increase Current Count
             CurrentCount++;
 
             // Add Platforms To Spawning List
             PlatformToSpawn.Add(Platforms[i]);
         }
 
         // Check if Current Count is Same as Next Count, while ensuring Next Count is not Higher than Array of Platforms
         if(CurrentCount == NextCount && NextCount < Platforms.Length)
         {
             // Increase Next Count (Number of Platform To Add)
             NextCount += 2;
             Debug.Log("Current Count is Same as Next Count!");
         }
     }
 
 }
