That's the golden rule of every handbook, included those of the venerated J. Brandt and S. Brown , but have you (or any) experience with 2.0/1.5/2.0 spokes? With classic usual DB, I never got problems (for decades).

Grab the time to wellcome the idea to push (gently) rims against wall/floor to relax spokes and (probably) unwind spokes winding. It sounds something better than nothing, a strip of dry marker can do check of.
