Why do the Jets continually use the short corner?

I have watched every Jnr Jets game in the NBN. I wish I had keep a note of every short corner that resulted in nothing. It would have to be close to 90% nothing. Not even a shot on goal.

Now, it appears the senior squad are short corner obsessed. Can someone explain why the Jets have decided to use the short corner as the ONLY method. Does anybody know of any top flight team anywhere in the world that uses the short corner as the prime attacking corner option?

I am over it!!!
