tyCarf "Grout" - meaning?

[Alexx31]

I was testing with tyCarf grout.

I read all descriptions, but still have no clear idea what it is doing.

It did a good job, when I did not have any stroke thickness.
And when the mesh is thick itself. (On thin meshes with small resolution at the cutted parts I did not see any effect)
After separation I had rough faces at the cutted faces, when it was set to iterations on "1".

I guess that grout is the rough displacement of newly ceated faces?
Is there any other parameter for grout to drive the noise only of this?

Or is grout just another cut?

Thanks or explanation

Grout duplicates existing cuts and changes the noise seed…this results in more details generated along cuts.
