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

[Rcmaster199 at aol.com]

Georg,
 
Entry (start position relative to center) and height will determine how the 
rolls are positioned within the diagonals. If the start is high, the legs will 
likely be long, and vice versa. The rolls will have to move accordingly.
 
An improved description isn't possible this time around therefore I suggest 
we live with this and educate ourselves in regards to judging it and flying it. 
We may change the description at the next rules cycle if we need to.
 
BTW, there are several maneuvers that are tricky, unfortunately. It's 
unfortunate because flying these things is one thing. Judging them CORRECTLY  (being 
educated about the possibilities)  is quite another. As judges we will be 
required to know the possibilities and NOT downgrade for them..... hopefully 
outlined clearly in the very fine offering of drawings courtesy of Rick Wallace
 
Rick is right.... it's important to have the dialogue here prior to the 
season's start and Nats so everyone is informed accordingly. I also know that my 
southern friends will chide me about the season's start since it already has in 
those parts of the country....Sigh!!!!

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! 
 
Rick
