ClickDelay for Flex app

Hello.
I need to test a couple of flex games and I wanted to do it with use of Sikuli.
Though I have a following problem:
Click on the button goes off only when ClickDelay = 0.20 or more but if decrease that value, then the click goes off less often.
For instance, for value ClickDelay = 0.05 I can visually see the click but nothing happens in the app itself.
I can use 0.20, it's not big of a deal but this is not a trustworthy way of testing.
I'm wondering whether I can somehow get a more reliable result? (something like "implicitly click delay")
Or maybe you can suggest some other way to do the testing?
Thanks a lot.
