> 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.
This is how I learned cursive in school, and it never occurred to me that this may interrupt my writing flow. I agree that doing the backtracks after writing the entire word would add to my mental load, but that's probably because I'm not used to that.
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.
