I'd say it's a combo of being more efficient and not as excitable. My BPs will wrap more coils if they are very excited at the time. but usually they just do as much as needed.

I've even had one "lose" the prey when she wrapped a lot.
The rat was under the biggest part of her body and she couldn't find it! After about 10 mins of searching, she settled down, waiting for another rat. When it was under her the whole time with just it's butt and tail sticking out!!!!

I had to pull it out for her. Then she's like "oh, there it is" and goes right to swallowing.

silly girl!
