The LCD of 10.2 ru established by #38 is involved in a wave front at 5 times the distance, as can be seen from the four points ranging from 40.8 to 41 ru. If you are unhappy with point #41--just ignore it.
This is a simple pattern operating on an LCD of 12.8 ru.
This chart has good visual symmetry if you believe in the accuracy of #94. All the other points are acceptable with an LCD of 6.6 ru.
Here we favor an LCD of 11 ru with point #3 open to challenge.
In this one we have an accurate LCD of 11.9 ru for the col at #35. We see that #91 (23.7 ru) is two-thirds of the distance of #97 (35.8 ru). The triangle formed by #24, #63, and #79 has sides in the ratio of 4:4:3. The fact that #79 and #24 are separated by 35.9 ru, which is quite closely divisible by the LCD for this pattern, helps to possibly confirm both the existence and the accuracy of the location of the seemingly obscure and questionable #24. Perhaps #24 is not a totally dismal choice for a point, since it is associated with a definite bend of the isobars in the immediate vicinity, indicating some disturbance. No incident, whether large or small, can be ignored by the points in the rest of the world--they must accommodate everyone and still conform to the laws of mechanics and symmetry.
Here we have two close-in points at 13.8 ru (#30) and 13.9 ru (#60), establishing the LCD.
There are three separate patterns (with separate LCDs) on this chart. The first starts with #87 (17.4 ru), which is linked to #96 (35 ru) and #9 (34.6 ru). The second starts with #88 (16.5 ru), which is linked to #82 (33.5 ru). The last one starts with #71 (23 ru), which is linked to #50 (46.4 ru).
This one has two separate parts. First we have the nearly equal spacing of #65 (2.3 ru) and #67 (2.2 ru). Second, we have #63 at 4 ru with #59 at 16 ru (another seemingly obscure point) at exactly four times the distance, and finally #78 (47.5 ru) approximately three times 16 ru or (twelve times 4 ru).
A simple gem. Four points divided into two separate pairs with symmetrical angles between each pair of rays. The distance between #52 and #9 is 60.5 ru, which is approximately divisible by 12 ru (the common LCD). There is a remarkable wave front of vortexes and a col at a very close average of 36.2 ru.
