Curious, how hard is the sample in the article meant to be? I grew up (in the 1970s) in a world in which cursive still ruled. But the variant that we were taught in school was already considerably evolved from the one used by my grandparents, and those were modern compared to the archaic German script ( https://en.wikipedia.org/wiki/S%C3%BCtterlin ) so I've never thought of myself as good at reading cursive. And of course haven't written (or read) much of it in the decades since.
It took about one minute to decipher the first sentence in the sample. Is that considered good these days?
