[NSRCA-discussion] From the Judges Chair

[George Kennie]

Boy, you guys got me wondering what all the hub-bub was all about so I had
to go and take a look and I think that I'm probably in partial agreement
with John. As I see it,It's simple geometry. After the turnaround it has to
be classified as a "center maneuver" and center maneuvers should be
centered !  The total width of the maneuver is equal to the diameter of the
loop, therefore the loop must be presented in a way that displays one half
of it's area, irrespective of it's size, on either side of the center line
which would require that the vertical upline be offset past center on entry
a distance equal to the radius of the loop. The loop is the key element for
the centering of this maneuver and the Aresti is incorrectly drawn IMHO.
Sorry if I muddied the waters here guys, but the forum appeared to be open.
Georgie
