In the Challenge, Section I.D.8 should read, “There are two options for creating the Testing Area. Option 1: The portion of the Testing Area marking the Measurement Zones will be made of felt fabric. Option 2: The Testing Area will be made of carpet squares. In either option, the edges of the Measurement Zones will be designated with hook-and-loop strips or painted onto the material with fabric paint or a similar type of paint. In either option, the surface of the Start Zone will be the tournament-provided floor; the surface of the Measurement Zones may have a 0.25in-0.5in (0.6cm-1.3cm) rise off the tournament-provided floor due to the thickness of the materials. (See Section I.D.12.)”
