Has been accurate for what I have assembled.. with some adjustment for all outbound or inbound spokes NDS.
The DT Swiss scenario gives 62 kgf NDS for a normal laced 32H.. goes to 83 kgf lacing 12 left... assuming 120 DS tension.
Hi WinterRider, interesting and exciting ... (120 * 0.52) * (16/12) = 83.2kgf
Lets workout a lacing we would like to try and build it (with your 5500 hub)

Hey WinterRider, Calnago and bm0p700f are absolutely right, but I wish they had suggested a NDS spoke lacing for a 16:12 arrangement
There are articles out there but you need to do alot of reading to find the information
Without >6 degrees NDS bracing angle (more like >7.5), and even though NDS tension is 44%, the wheel would not be laterally stiff.
Because DS bracing angles are so small ( <4% ) the NDS brazing angle becomes critical.
It would appear that the closer the NDS bracing angle is to 6 degrees the more the DS brazing angle needs to be closer to 6 degrees.
You could say that the DS and NDS brazing angles need to add upto about >=12 degrees
The issue with reducing DS brazing angle and increasing NDS brazing angle is that the NDS spoke tension proportionally drops by the same ratio
- If DS bracing is 4 degrees and NDS is 8 degrees and the DS/NDS spokes are equal (16:16, 12:12), then DS spoke tension of 120kgf and NDS will be 60kgf.
- If DS bracing is 4 degrees and NDS is 12 degrees and the DS/NDS spokes are equal (16:16, 12:12), then DS spoke tension of 120kgf and NDS will be 40kgf ...
Using DT Swiss 240S hub, 130mm OLD, rim ERD 555mm, 32H 16:16 hub/rim, will give a 52% NDS ratio ... if DS spoke tension of 120kgf then NDS will be about 62kgf
- for 3x pattern ... DS bracing is 3.6 degrees and NDS is 6.9 degrees ... Total Bracing angle = 3.6 + 6.9 = 10.5 degrees (good torque control, average lateral wheel stiffness)
- for 1x pattern ... DS bracing is 3.8 degrees and NDS is 7.3 degrees ... Total Bracing angle = 3.8 + 7.3 = 11.1 degrees (average torque control, better than average lateral wheel stiffness)
- Spoke pattern affect Torque Control (Climbing/Sprinting) and Bracing Angle
- Flange diameter (Spoke Circle Ø) affects Bracing Angle ... especially the DS flange Spoke Circle Ø due to DS bracing angle being <6 degrees
- DS/NDS Bracing Angles affect a wheels lateral stiffness
A hub with wider Flange spacing (FTF) would be better ... ie. NDS flange offset (LCF or CLF) > 34mm and FTF > 54mm ... such as the Novatec = 38mm/56mm, BHS SL211 = 37.75mm/54.5mm, and others ...
The Chris King Classic Cross 130 OLD hub is interesting in that CLF = 37.3mm, CRF = 17.2mm, FTF = 54.5mm, Spoke Circle Ø = 53mm/53mm
- 3xDS 3xNDS 16:16 ... Total Bracing Angle = 3.7 + 7.9 = 11.6 degrees (good/excellent torque control, good lateral wheel stiffness)
- 2xDS 2xNDS 16:16 ... Total Bracing Angle = 3.8 + 8.2 = 12.0 degrees (good torque control, good/excellent lateral wheel stiffness)
Theoretically, if our hypothesis is correct, using a 32H hub, 130mm OLD, 28H Rim ERD 555m, CLF = 40.0mm, CRF = 16.0mm, FTF = 56.0mm, Spoke Circle Ø = 53mm/53mm, NDS Ratio = 40%
- if DS spoke tension = 120kgf, then NDS spoke tension = (120 * 0.40) * (16/12) = 64.0kgf, Corrected NDS Ratio = 53% (just an acceptable NDS spoke tension/detension stiffness ratio) 
- 3xDS 3xNDS 16:12 lacing ... Total Bracing Angle = 3.4 + 8.5 = 11.9 degrees (good torque control, good lateral wheel stiffness)
