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...
