The tightWavesExample01.duf is looking for textures that aren't there - the Journeyer scout textures I have are without an addition _DC at the end of the name ... but the hair looks great!
OK, I had fun (I did read the readme to the last line

)
When playing too long, DS crashed ...
The first time I created a primitive sphere and played with all the tabs until I came to the Tweak tab. That was reacting very slowly, and then ... crash.
Restarting DS and redoing that and the crashes came early, even when just painting the Density map.
Now it crashes each time I am trying to select a second part of the hairs to style.
Sometimes I get:
DAZStudio.exe caused ACCESS_VIOLATION at 0033:000000000981F786
Sometimes the whole thing grays out and after some time
Sometimes I can't paint the density map ... closing Garibaldi and Edit / Edit Garibaldi hair again worked.
Is it possible to select all the guiding hairs?
Like "adding to selection"?
Answering myself: listen to the video: shift + click+ drag
