I'm no expert, I only play on on the forum, but my early instructions were for DCS RRs to isolate all rails of each block and directly feed non bundled twisted star wiring with two single wires directly from power source to each block attaching to just one end of it. Not in the middle.
Do those instructions from a long time ago still hold true?
I read so many comments of folks who do not use that pattern yet claim strong readings?? Perhaps other variables at play??
