<div>As Chair of the sequence committee the intent was that the
      maneuver be square, equal horizontal and vertical.  I have
      searched for the maneuver descriptions that include that the
      horizontal segment of any top hat must be inverted and I I was
      unable to find that reference (everyone agrees on this point).  I 
      believe that there is also a reference to the line lengths on a
      center top hat maneuver being equal.  Pretty sure that they have
      always been so in the past.  If anyone can find that document that
      discusses top hats please let me know.</div>

    
<div>I apologize for not including that downgrade in the maneuver
      descriptions.  (another vote for having a document with basic
      downgrades for each maneuver type for future sequence committees
      to use.)</div>

    
<div>If not including the downgrade in the maneuver description
      changes the maneuver that was intended, I also apologize for the
      oversight.</div>
