Obviously the letters connect, but where a given letter ends depends on the following letter, and where a given letter starts depends on the previous letter.

For example, in standard American cursive, b, o, v, and w have a top exit stroke, whereas the rest of the lowercase letters finish on the writing line. Combine this with the letter a, which has a top entry stroke, so the oa will join at the top, whereas ea will join from bottom to top.

I don’t see how this matters? They’re splines right? Just quickly writing those down I see a very minor variation in how they connect, but ultimately that variance’d be hardly noticable.

Regardless, the end of the o or e, to the beginning of a is still a straight line.

The article gives explicit examples of where just connecting them with a straight line does not look right, and is noticeable.

Absolutely, and that’s how I can see that it has more to do with the form of the letter than the fact that joining without adjustment is impossible.

Anyhow, I doubt we’re going to convince each other here. Since the tool is right there I might just give it a try.

At this point I'm not sure what we're disagreeing about :)

Interesting. In the 90s in Germany I learned that for some letters you lift the pen, even though the result will look connected, e.g. "ac" would lift after the a, draw the c leftwards, touching the end of the a and then swing around to the next letter, kinda like this, but leaving no gap between the letters: /C

Also, t would be disconnected with itself, being written like /| followed by a - overlapping the |
