Is my frames per second counter correct?

Iam pretty bad at scripting with unity
But i neaded an true fps counter to se in game framedrops and such.
I have used an delay counter so that you have time to see the fps, as they flicker to fast without it
Is this correctly done?
Simply wondering as the counter goes from 49 - 110 fps constantly.
Dropping down to 49 seams pretty bad with so little going on on the screen?
The built in editors fps counter in the stats clocks around 600-900 fps and with an max of 24 drawcalls.

Code (csharp):

1.  
2. var show = false;
3. var delay = 0.2;
4. private var nextdelay = Time.time + delay;
5. private var oldfps = 0.0;
6. function Update () {
7.     if (show){
8.       if (Time.timeScale != 0.0 Time.time > nextdelay){
9.       nextdelay = Time.time + delay;
10.       var fps : int = 1.0 / Time.deltaTime;
11.       guiText.text = fps.ToString();
12.       oldfps=fps;
13.       }
14. guiText.text = oldfps.ToString();      
15.    }
16. }
17.  
18. @script RequireComponent(GUIText)
19.

The frame counter in the stats only tells you how long it takes to draw the graphics.
