Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Yes, basically the only thing tha you need to do is count 7 rounds from the clock of your ds (the little clock that appears when you are sending your poke over the gts) and when the little clock is going to the 7 rounds and a half you turn of your ds.
Obviously it needs several tries for clone a poke.
Usually i always turn my ds at 7:35, just to give you and idea of the rounds (seven rounds and a little more than a half before completing the 8 round)
