Um, that appears to be an Italian tour site? But, I have heard this mess before.
This is pretty much like Dilbert math here. An arbitrary percentage isn't ANY industry standard or a good recommendation. Saying 20% is the number implies that the engineers that designed each brand and model truck intended you (or the average truck consumer) apply that arbitrary "standard". They didn't. And at the very least, they didn't agree to 20%. That would mean they all agreed to this allowance, and we can barely get them to agree to put their trucks up for S.A.E. standard ratings. (which some have now done)
The engineers that design these vehicles almost certainly put a safety factor in their calculations. That safety factor may of may not be cut into by some marketing or management genious, but . . .
