Okay.
I also wanted to have you talk about the graphs showing sleep in the deployment cycle. We see the data during deployment periods, and the actual hours of sleep, as you said, or the perceived hours of sleep that the individuals in the study report. Does the methodology take into account the fact that certain operational constraints during deployment, such as guard rotations or interrupted or unplanned night operations, prevent a person from sleeping? During deployment, soldiers don't necessarily get to sleep for eight hours, even if they want to.
