Ball toss in kick serve

No, I'm not going to ask where you have to toss in order to be able to hit kick/twist. What I want to know is where your tossing arm is supposed to start the toss to get the ball behind you.

If you take a look at that picture, would you start the toss from the slice point(0 degrees) or the topspin-slice point(45 degrees)?
