How to square handwriting variation?

[JoJo_Jost]

The answer is likely 'there is no answer' but I wonder to what degree the communities efforts is split on small variations like these and how much it obfuscates the text itself.

Of course it makes a difference, and here you can see it very clearly. As we know, these small letters stand for omitted letters.

The sign which looks like a mirrored c, stands for “us, os, is, s” so the letters can be inserted here. But also a 9 with a straight tail pointing downwards. But mostly at the end of a word.

The y stands here for "er", which will give the word a completely different meaning. 

The hat, i.e. the last ligature, also exists, but I can't find it right now (there are 14,000 ligatures in the dictionary) and it has yet another meaning, but it could also be a faded 9.

And to make matters worse, the "u" for “ur” could also be written with a tail pointing downwards, which looks similar to a 9, but has a different meaning.

So it is important. Similarly, the two “c”s in “ch” can also represent different letters.

And to make it even crazier, the letter can simply be the extension of an S, as is done in the "sh" transcription. And the mirroed S as a con = conc...

Normally, this is clear from the context... big laugh here...

I won't even mention the line between the c's...   sh =  conmc (joke)????

   

   
Übersetzt: A very similar sign to "us" is sometimes found above certain consonants with the meaning “er,” but not at the end of the word, as in
