Ah yes, I remember spending ages on this problem. I dont think I really found a solution to it other than living with it. There seems to be no logic as to where in the letter the points start or finish.
Calculating the length between adjacent points might work.
From what I remember typospread has a few weird things about it, if you want to actually have nicely set text especially over a few lines - but its possible. I ended up making like an editor, where you can position, scale and rotate each letter individually.
Ah yes, of course. Just opened the patch to have a look. Instead of using Line to connect the points in the typospread, you just use points. If you use enough of them you will have a continous line without those weird connection lines.
You can use a 2-step approach where you have not so many typospread points and then use resample with various resampling methods to get different effects and end up with the many points needed to make them look like solid lines. Dont worry, vvvv can handle it ;)
