Stuck in While Loop ** Cant find why!

I am stuck in a while loop, can someone tell me how this below is infinite?

• Debug.Log(StartAt) = 10.15

• Debug.Log(ReloadTime) = 2

  ---

My logic is...

• +/-600frame (Because my FPS is around 600) the float Progress will equal 1

• So in approx. 1201frame the float Progress will equal 2.1.

• Then Progress = 2.1 will be greater then ReloadTime 2

     private void OnReload(float Reload)
       {
           Reloading.SetActive(true);
   
           float ReloadTime = Reload;
           float StartAt = Time.time;
           float Progress = 0;
           double Fill = 0;
           double FPS = 0;
   
           while (bIsReload == true)
           {
               FPS = 1.0 / Time.deltaTime;
               Progress = (Time.time) - StartAt;
               Fill = (1 / (ReloadTime * FPS) * (Progress * FPS));
   
               Reloading.GetComponent<Image>().fillAmount = (float)Fill;
   
               if (Progress > ReloadTime)
               {
                   bIsReload = false;
                   Reloading.SetActive(false);
               }
           }
       }
