If you have built as I have very low spoke count wheels you get a wave set up that is difficult to control hense extremely stiff rims are required. I used a 88mm deep rim for a 12 spoke wheel it was manageable on that and I have a stable wheelset (not one I would build for any one else though). A shallower conventional rim laced with the G3 pattern would have roundness and lateral trueness issues that vary from wheel to wheel.
To maintain consistency Campagnolo use the G3 pattern and an rim specifally made not to be round that becomes round when properly tensioned, unlike a conventional rim which has to be round to begin with and will still be round when tensioned. Correcting out of roundness on a conventional rim will lead to spoke tension variation (with modern rim fairly big tension changes are needed to correct even small deviation) and this leads to accelerated spoke fatigue.
The redish will change the bracing angles and therefore the tension balance so it is not true the tensions will remain the same after the redish as before.
On the last superX wheel I did with a rim ERD of 545mm and a Miche disc brake hub normal bracing angles would have 4.4/7.5 degrees. After the 6mm redish braing angles are 5.7/6.2 degrees. So yes the zonda wheel after redish would have higher NDS spoke tension than the DS. It is not true to say that any redish will have the same tensions as the wheel before. Any change in bracing angle alters the tension balance.
So stormur before passing judgement know more about what you writing. Also try not to cast judgement on people you have never met and the work they do.
to make your loong story short : BS.
Instead of telling to others what to do, apply your advices to yourself.
