HIC SUNT DRACONES

[sdi]

 

A geomantic chart contains 1.75 dragons on average. (My daily geomantic charts contain 2.10 dragons on average.)

The chance of a chart containing a given number of dragons is:

0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
19%	28%	26%	16%	7%	2%	<1%	<1%	<1%	0%	<1%	0%	0%	0%	0%	0%

Interesting! If you graph this, it looks a bit like a probability curve with a very long tail on the right.
Have you mapped the probablilities of all 16 of the figures on that scale? If so, are the probabilities all similar, or are some of them quite different?
If you did Populus and Via, for example, there would be a percentage in the '15' slot, since it is possible to have an all-Populus chart, but not possible to have an all-draconis chart.
I suspect that Conjunctio/Carcer and Via/Populus, which have internal symmetry, would have a graphs similar to each other...

Your wish is my command...

They're all pretty similar; the differences are mostly down to whether the figure is even or odd (even figures can appear in Judges, and so are more common: even figures appear once per chart on average, while odd figures appear 0.875 times per chart on average) and in those rare charts where the figure dominates.

Thanks!
There are no figures that have 12, 13, or 14 members.

The groupings of identical rows are also interesting to me. This might be a new form of companies-- Company simple, demi-simple, compound, and --frequency?
