Wheel building, tension too high?


I have a high drive side tension 1.8mm round spoke indicate 24-25 on the park tool TM-1 which is 148 kgf for 24 and 167 for 25...!
The non drive side is going around 17-18 which is 70-77 kgf.

I am building the BDOP DIY allow kit and he recommend 110-115 on the drive side.

These are based on recommendations from Sapim. The rims are fine with that, and more. The hubs don't have a limit (at least not one that has ever come up in 7+ years).
The wheel is nearly perfect in term of alignment (lateral and radial), it moves around 1mm at some places, the tension is pretty even on the NDS & DS. The hub is almost perfectly centered, a tad more tension on the driving side would bring the hub in the middle but the tension is already high...
I am just concerned with the tension. I compared the DS (drive side) tension with other rear wheels and it is very high. My R500 shimano have a 2.0mm round steel spokes and they hit 28 (173kgf).
I wonder if I should reduce the tension and if so how to properly adjust the wheel. Only way to reduce the DS tension is to reduce the NDS and it's already somewhat low...
