Aziyade, you're a legend, such a simple idea that it's ingenious!If, however, you want to have nice clean and sharp shimmies, 3/4 shimmies, drops, whatever -- do yourself a favor and buy a metronome. A cheap one is like $4.99 and it's WELL worth it. Get out the metronome, wind it up, and set it for a low speed. Like, a boring death crawl speed, okay? Seriously. Practice the movement for maybe 1-3 minutes -- whatever you need. Does it look sloppy? Stay at that speed and continue practicing through the week/month. Once you get it where it looks nice and clean -- then and only then should you click the metronome up a notch (just one!) and practice at that speed.
