But the thrust of my posts remain unchanged. While an offset rim will help reduce the R/L tension imbalance, there's never enough offset to affect spoke length enough to factor in a spoke length calculation. If the OP is concerned, he can adjust the CTF measurements by ±5mm respectively and doing a test calculation. That may not be the exact offset, but is plenty close enough for spoke length calculations.
I agree for the most part...
What really gest me about his thread now though is the reply supposedly from DT Swiss. Most narrow OSB road rims will be +/- 2-4mm against hub offsets resulting in about .50mm in spoke length change....yet the DT Swiss reply when reverse calculated suggests an offset of 10.00-11.00 millimeters putting leaving the nipples embedded in the CNC work of the sidewall. (It's 21mm wide rim...)
Makes me wonder if the DT Swiss rep was just giving the respondee a quick off the head remark just to get them out of their hair...
