Reliability in mesuring short time

[Perkulator]

Is it a good idea to create a time reaction test i flash? A sound signal would make the user klick the mousebutton or press a keyboard key. The program would mesure the time elapsed from the soundstart to the keypress.

How great would the reliability be in mesuring a very short reaction time in a case like this? Or rather, how big would the range of uncertainty be? I mean, on the web, in a browser. Which browser, how many processes are running at the same time, what kind of computer and operating system and so forth. Could you get any reliability at all?

If it's delivered via internet you'll encounter the same variables as web browser, but you can download everything before you start your movie so that at least you can eliminate download speed variants affecting adversely. The clock itself is based on the computer clock and thus it's more to do with the OS rather than Flash.
