[NSRCA-discussion] K-Factor Maneuver description and judging

[george w. kennie]

Boy, I love that Anthony. He really stimulates my brain ( however small it may be). I spent about 2&1/2 hours Sunday afternoon drawing out this maneuver in differing scales trying to understand why the roll position varied with different presentations and was able to finally determine that the entry point is the culprit.
The original maneuver was designed to represent a golfball sitting on top of a tee. If you take your K-factor and turn the page upside-down you will see what the thing is supposed to look like in the first drawing. In the second drawing the tee is extremely small and this is because the entry point is late ( too close to the center of the maneuver). IMO, the maneuver should be performed in a way that presents the overall form with relative symmetry between the upper and lower halves of the total maneuver. 
If the entry point occurs at a point on a vertical line drawn tangentially from the extreme radius of the looping segment with this line intersecting the center of the first 1/8th radius, then the rolls will occur exactly on the center line of the maneuver and the baseline (imaginary) of the tee will equal the diameter of the loop and the total maneuver will be in symmetry.
I feel that the symmetry requirement should have been included in the descriptor in order to achieve standardization in the judging criteria. Applying the existing criteria to this maneuver is almost like scoring last year's TO's & Lndgs. I predict that there will be many a disappointed pilot this year when they get their sheets.

  It's working: early-season discussion of new maneuvers. Perfect!

  In our early discussions, one of the authors of the sequence protested that he'd envisioned the 1/2 rolls crossing at center, and just last weekend when I was practicing, I automatically tried to position and size the maneuver so that the 1/2 rolls WOULD be on center... but they don't have to be for a max score. 

  Wayne and Matt nailed it - the maneuver description simply states that the the rolls are centered on the 45 lines, not that they occur in the center of the maneuver -- and there's a difference between the two.  It is possible to fly this one correctly in several ways, and each way should be judged accordingly.   As judges we'll need to score against the maneuver description which is the standard, not a mental image or set of assumptions... 

  Keep it coming -this is great!

  and btw, it IS all Anthony's fault, like he said!

    The issue was debated by several of us who contributed to the definitions. The maneuver description doesn't say nor does it imply that the rolls must be on the center pole, although THAT IS ONE OPTION.  The drawings and explanations are correct as indicated. Wayne is correct about the radii of looping elements

      The rolls just need to be in the center of the line segment of each 45 line. 
      The whole maneuver including line segments must be on center.  The half 
      rolls will not necessarily intersect at exactly center pole or on top of 
      each other, but the lines of the 45 cross or intersect at center.   The 1/8 
      push radius and looping segment have equal radius.
