[NSRCA-discussion] From the Judges Chair

[John Gayer]

Derek,
"Somewhere in the 3/4 loop portion" is awfully vague and unjudgeable. I 
could buy anywhere in the 3/4 loop portion but not somewhere.
The center you are describing would appear to be affected somehow by the 
entry and exit lines of the maneuver as per your description in the 
March K-Factor. I don't see that. This maneuver(figure 9) could be 
described as a single loop with a straight vertical line between the 
first quadrant and the last three quadrants. What rolls occur do not 
affect that basic shape. That places the center of the maneuver at the 
initial pullup into a quarter loop just as it would for a simple loop. 
The apex of the 3/4 loop would also be on the centerline and so would 
the return to level flight at the exit.
As far as the straight line entry and exit being somehow offset, I don't 
see that either. The entry line ends at the quarter loop pullup and exit 
line begins upon completion of the 3/4 loop. Those two points should 
form a vertical line. I see that as the maneuver centerline as well.
It's certainly true that the aresti shows the wrong center and it is 
certainly true that the sub-committee chair has the last word but he 
should be using a better word than "somewhere".
