Benchmark score resuilt script

Hello, i need our help because i dont know how to make this script. I am making a benchmark test with Unity3D, and for FPS show i use script from wiki FPS_Display.boo. I need a script who will check a FPS value from FPS_Display.boo every second,calculate resuilts,and show final resuilt after 60 seconds. So,if FPS value 30 every 1 second,and script will show a resuilt in 10 seconds,it should show 300. Thanks every one for help, sorry for hard question,because my scripting is bad.
