Pretty simple execution, Ttar comes out and most taunters, fearing retribution, will be switched out. This is the turn that t-wave is used. Next comes the set up of stealth rocks and then the roarwaving can begin. Chople berry ensures that if the enemy starts with a strong fighting move (think Infernape with close combat opener) that the TTar will survive and t-wave them, gaining the speed advantage and setting up the rocks.
Most people see Ttar's awesome attack stats, and forget he has a VERy solid defense and special defense. Add the fact that he gains x1.5 special defense in a sandstorm (the above set brings him to 400 spdef) and you have a very solid wall for an opener that many people do not expect.
You haven't been able to find a reliable damage calculator? http://www.smogon.com/calc/
If you're only going to have one attack, wouldn't you want one more reliable than Stone Edge? Also, what do the EV's do?
