100kg force sounds like the right ball park to me, on the low side if anything. 70kg force is on the edge of shaking loose with regular riding, and close to what I would be forced to accept on the non-drive side of a wheel for a campy 10 or 11 speed wheel (same offset for those two drivetrains).
Rim manufacturers will always be pretty conservative on what their rims will take. The polar opposite is builders like Jobst Brandt who AFAIK will tension a wheel till it pretzels and then back off a fraction. Optimal, in my view lies between those extremes. Oh, for carbon rims I take the rim manufacturers at their word.
