Yah, the delay simulates the on/off of force move. The smaller the delay the more you spam. This will give you an effect of a blinking circle next to your mouse pointer as you can see in the video. I recommend putting the macro on the mouse since I saw a better performance since my FC is on my keyboard and spamming to many keys with macros can lock up your keyboard.
Thanks again. I hope you don't mind but I shared your video on the Blizz forums. People have been asking like crazy for something that works without having to shell out money for something that will be obsolete in 6 weeks
