Well, I've done Search and Rescue, and the one thing I have learned is that what you do in a training scenerio and what you do in a real life situation can often be completely different. I've seen amazing acts from people I never thought could do them, when they were the only hope. If those people seriously thought a loved one (obviously a child from the size of the dummy) was in danger, they may perform much better. The body is an amazing thing and can produce strength and stamina when none existed before.
