When you're just starting with two poles then can click and throw as they commit/enter. There's...two poles.
As you add poles, you throw as they are exiting which is why it's important to throw consistently down the pole line. You don't want them slowing or turning to look...you want them already knowing where that fantastic object of their deepest desire is going to appear, and driving for it. I don't use the clicker much at all after the two pole stage. "Scalpel", and all that.
Later when proofing you can throw while they are in the poles to validate their understanding of the Task, the whole task, from start to end. But that's later.
