The Origin of [sh]

[Wladimir D]

Below are examples of "words" broken down into several groups that combine "words" with certain characteristics. Elements (component parts) of these examples take part in EVA-sh.
   
I group. - a compound line (1, 2),
- Is the horizontal line in examples 3, 4, 5 just a connecting line?
- I have big doubts that in examples 6-9 the apostrophe is written over EVA-h. This opinion follows from the ІІ group.
- There are examples of self-writing a horizontal line with an apostrophe (10-12).
ІІІ group
Writing EVA-e with a gap. Since the "e" in this case is omitted, it seems to be added at the last moment when they wrote a line (17), "h" (18-20) or a long bench (21), EVA-I left foot of this bench .
In example 21, the bracket is also added to the already written bench.
 IV group - The apostrophe is written not only over the benches!
V group - writing EVA-c & h with a touch of the gallows. Of particular interest are 36, 37, since there is no continuation of the line inside the gallows.
VІ group
Strange ligatures. Moreover, the ligature 43 is not taken into account either in the expanded EVA, neither in V101, nor in the Jim Reeds table. You are not allowed to view links. Register or Login to view.
Strange ligature 45. I met three such cases, but I publish this one, since three elementary strokes are clearly visible here.
VІІ group - horizontal line
   

VІІІ group is a point (blot) in the left or right foot of the bench, and it is smaller in height than EVA-e ©. If it's just a blot, then why does the left foot of the bench turn into a blot 30 times more often than the right foot, despite the fact that the pen movements are the same. In this case, the ratio should be close to 1: 1.
The ІX group is EVA-o and the point (blot) in one "word" (58, 59, 60). The height of the point (blots) is also less than "o".
Point with an apostrophe (28, 29).
If we consider these groups as a system of equations with a large number of unknowns, then the private decision (explanation) of the system is that the bench sh can consist of separate (independent) symbols "e", "i", "-", "•" and an apostrophe .
The location of the apostrophe (in the beginning, in the middle, in the end of the bench) can indicate both the specific character missing in the main line and indicate that there are no symbols (after the first "e" or "•", after "-", after the second " e "or" • ").
