Building my own benchmarking program

So, I'm doing some research for my next game. I want to know how many polys the Web Player can take. I make an empty scene and made a script that instantiates an object with 1000 triangles every .01 seconds. It will instantiate it within a box 200 units wide. I have the camera going around in an animation pattern.

You can play it here: https://dl.dropboxusercontent.com/u/33872519/FR%20Test%20Build/FR%20Test%20Build.html

This should give me an OK benchmarking program, right? I mean, I know that AI scripts and the like will slow it down, but this is a good ballpark, right?

Script below (in UnityScript): #pragma strict

 var object : GameObject[];
 var guiVerts : GUIText;
 
 var waitTime : float;
 
 var numOfVerts : int = 0;
 
 var theBox : float;
 
 private var goAhead : boolean = true;
 private var wereDone : boolean = false;
 
 
 function Update () 
 {
     guiVerts.text = "Number of Vertices:  "+numOfVerts.ToString();
 
     if(Input.GetKeyDown("escape"))
     {
         wereDone = true;
         Debug.Log("escape");
     }
 
     if(goAhead)
     {
         SpawnObject();
     }
 }
 
 function SpawnObject()
 {
     goAhead = false;
     
     var modelNumber = Random.Range(0, 3);
     
     var randomNumX = Random.Range(-theBox, theBox);
     var randomNumY = Random.Range(-theBox, theBox);
     var randomNumZ = Random.Range(-theBox, theBox);
     var pos : Vector3 = Vector3(randomNumX, randomNumY, randomNumZ);
     var clone = Instantiate(object[modelNumber], pos, transform.rotation);
     
     numOfVerts += 1000;
     
     yield WaitForSeconds(waitTime);
     
     if(wereDone == false)
     {
         goAhead = true;
     }
 
 }
