Hi,  At a recent 2024 invitational, the Laser Shoot was setup with a barrier mirror on the midline plus one additional barrier not on the midline.  This was Div B.  Our interpretation of the rules is that for Div B, there are no additional barriers.  Rather there is only the one barrier mirror somewhere along the midline.  Please clarify whether, for Div B, students need to be prepared for more than one barrier.
