While we're sharing anecdotes, my handwriting is remarkably terrible, and the iPadOS Notes app does a good job of transcribing it.

I think this supports the grandparent's point about using the actual strokes, including angle and azimuth, to reconstruct intent.

I was also fairly proficient with Graffiti, back in the day, but I consider that an input method, not handwriting recognition. I was facile with T9 as well.
