How to create a Flash Performance Calculator in AS3

This is a simple AS3 performance calculator I created..

/*********************************************************\
|*Thanks for using Fighterlegends performance Calculator!*|
\*********************************************************/
var documentFPS = stage.frameRate;
var lastTime = getTimer();
var samples = new Array(30);
var frameCounter = 0;
stage.addEventListener(Event.ENTER_FRAME, update);
function update(event:Event) {
	var currentTime = getTimer();
	var timeDif = (currentTime-lastTime)/1000;
	lastTime = currentTime;
	var actualFPS = 1/timeDif;
	samples[frameCounter % 30] = actualFPS;
	frameCounter++;
	var averageFPS = 0;
	for (var i = 0; i < 30; i++) {
		averageFPS += samples[i];
	}
	averageFPS /= 30;
	var performance = Math.round(averageFPS/documentFPS *100);
	var lag = 100-performance;

	fps.text = Math.round(averageFPS) + " fps\n" + documentFPS + " target fps\n" + performance +
	"% performance\n" + lag + "% lag\n";
}

Just create this dynamic box on the stage:
Instance: fps
width: 140
height: 84

Hope you give me credit!

UPDATE:
I got a new, and better update of the script from WarKry on Kongregate!
