I see in reV4 that you abandon 'RuleSrf' using the two spirals in favor of lofting lines, so I compared the two and agree.  The image below shows baked 'RuleSrf' on top and 'Loft' of lines on the bottom.  Much cleaner isocurves from 'Loft', so I changed my version too:

Sticking with 'Extr' instead of 'Offset' surface though; small but important construction detail.

Is there any part of this project that you are able to write yourself or are you just the art director?

I noticed the flaw in my first version due to 'Crv CP' - it only showed up when the spiral width was ~7 or greater, which is more than the vertical distance between "threads".  So I used a different method for plotting the offset points.  I also changed the way the 'RuleSrf' is thickened, using 'Ext (Extrude)' instead of 'Loft', because loft failed.

Thanks Joseph Oster for answering.
It's kind of architecture student project.
