Penelope decided to start by practicing the incantation and the wand movement separately. Not only was she inexperienced with the spell, but she did not want to pull dummies toward her. She liked her personal space circle, and did not want to do anything that might involve something getting in her personal space circle.

Incantation first. "Carpe Retractum! Carpe Retractum! Carpe Retractum!" The first year repeated the incantation until she was sure that she had it right.

Now for the wand movement. She tried the wand movement a few times. Whip like movement. Penelope decided to practice it a few more times before trying it on a dummy.
