You only need 1 backtrack if you do the dots and crosses after you've written the word
> One way to remove backtracking is to lift the pen immediately instead of waiting until the end of the word, as if doing italic calligraphy. Pen lifts alleviate the mental queue problem and give a chance to readjust the palm, but they break the writing flow.
So generally, I'd say that the mental load is basically a matter of how one learned cursive in the first place. Though I agree that the mostly backtrack-free Cyrillic cursive looks more elegant.
Would be interesting to learn about the perspective of people who learned Chinese or Japanese as their first script.
I've gotten comments about how neat my Chinese writing is from people surprised that I don't use handwriting. There's a simple reason for that: I've never learned how to do Chinese handwriting.
