I ran it for both 3x and 4x and noted both. 3x and 4x are so different from one another that it would be impossible to mix them up. I just checked my notes--for 4x I came up with a front hub spoke length of 300.1 (vs. 288.9 for 3x). For the rear wheel, I came up with 298.7 on the drive side (vs. 287.5 for 3x) and 300.7 on the non-drive side (vs. 289.5 for 3x).
My notes on hub measurements for the front: D=67, S=2.6, A=16, B=16, WL=34, WR=34.
For the rear hub: D=67, S-2.6, A=25, B=46, WR=17, WL=38. I haven't run the numbers again myself--I haven't had the heart to, and now I know what size I need based on direct measurement of how short the current spokes are. But obviously, it would be nice to now what I did wrong for future reference.
