When I try to increment a variable by 1, why does it add 10?

In my code, i wrote

   function CoUpdate ()
     {
         while (GameManager.xMovement > 0)
         {
             transform.position.x += GameManager.xMovement + .01*Deleter.timesDestroyed;
             yield WaitForSeconds(1);
             GameManager.totalMovement++;
             if (GameManager.hasFallen == true)
             {
                 //xMovement -= .001;
             }    
         }
     }

The part that is causing concern is the GameManager.totalMovement++;, because when I view the variable within Unity as my game is playing it increments by 10 instead of by 1. Why is this? The code to display the variable is

 #pragma strict
 
 var sphere : Transform;
 public static var hasFallen = false;
 public static var xMovement = .085;
 public static var totalMovement = 0;
 var xMovement2 = .085;
 var totalMovement2 = 0;
 public static var waitDone = false;
 
 function Start () {
 
 }
 
 function Update () 
 {    
     xMovement = xMovement2;
     totalMovement2 = totalMovement;
     if (sphere.position.y <= -20)
     {
         hasFallen = true;
     }
     
 }

Also, when I try to increment a variable by a decimal, the value does not display in Unity as it updates in real time. Why is this?
