+1    Though admittedly slightly scared that I'm agreeing with George :)

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.

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".

Anthony,

This shouldn’t be confusing at all… the center of the maneuver is the middle point between the start and end of the maneuver.  How much more simple can it get?   The statement that the “middle should be somewhere in the ¾ loop portion” is correct – depending on the size of the ¾ loop which must match the radius of the ¼ loop from horizontal to vertical when the maneuver starts.  That center portion will change for every pilot as each pilot will fly it differently.

Your comment about “many outside the US” isn’t accurate – if they see it differently then they are incorrect.  The clarification I got is straight from the F3 sub-committee chair…

Would love to see a review of maneuver 13 of the Finals sequence. In the March Kfactor the center was described as "should be the middle of the maneuver somewhere in the ¾ loop portion." While the many outside the US see it that the loop is centered and the Aresti in the latest FAI sporting code show the upline being centered.

A bit confusing,

Anthony

Hey guys - we got an excellent suggestion from the group for last month's article so I thought I would ask again! Anyone have a burning maneuver or judging question? Just let me know.

Thanks,
