I understand your tolerance stack consideration. It certainly would come into play based on the numbers we're tossing around.
There is also a lot of chatter now, esp about deep dish carbon, and where the actual flex is, how it affects tracking and power etc, and spoke tension should be part of that conversation.
Another thing to consider is what the properties of the spokes Zipp uses are and if perhaps they are drawn to specific spec for their very specific use: Zipp rims. Of this I am not knowing.
I think tis is becoming a sidebar for another thread.
