Historically, some callers used concepts such as
    
Diagonal Box,
    
Jay,
    
Once Removed
    or
    
Trapezoid
    with this call.  They wanted you to evaluate whether you are an End or a Center in the entire
    
8-dancer formation and then do your part of the call working in the
    given formation.  This usage is typically frowned upon today.
