You may consider adding a trigger flood control, because you'll still get flooded with repetitive commands being sent to the client that runs the code. It doesn't matter if every message is timed. You'll still receive a bunch of timers being set and get overwhelmed with text flood if some people try to tamper the script and screw with you. You may say the likelihood is not going to be great for yourself, but you can't speak for other people who might take your code to use and not run the risk of being flooded.
