… you must look into the Data Tab for trimming the parameters and playing with them.
CurvesWB is experimental and ChrisG has a lot of "eastereggs" in, therefore this WB is very surprising.
The "shadows" of triangulation relicts can be reduced in View Tab by choosing a smaller refinement value.
The multicolor wireframe is something weird and I see no use.
Sweep_2_rails has also some tuning tools (point, frame, wireframe.., number of frames …) in View Tab.
You get it by experimenting. There is no manual, only forum posts - you're already gathering and linking.
Learning by doing and I hope this tutorial thread will help ...
