Yura didn't see any harm in this practice. The worst that could happen would be the bowstring breaking and snapping back on him. When Sasuke popped his head back in Yura got to her feet. Then outside she held out her hand to take it from him and looked it over. 

"Looks like it's in good shape."

She examined the arrows next and nodded. There were only a few of them but at least if she did snatch them out of the air they wouldn't get ruined. Yura gave them back.

"Alright, pick a target and do a few practice shots." 

She really did intend to make herself the target soon but she wasn't sure she could or should get him to actually fire upon her right away. And besides she could examine his technique far better from here and make adjustments if he'd let her.
