I have never strung a liuto attiorbato but the principles should be exactly the same as for any other lute with an extended neck such a swan-neck 13-course. I find that the longer the string length, the more tension you have to put on to get the same feel under the fingers. Similarly, for a small instrument (such as a 6-course in a') the tension has to be considerably less.
I find the string calculations given below to be rather odd. Personally I would definitely put more tension on the bass strings (I would aim for a little over 3Kg on the bass strings of the lower neck and say 3.2Kg for those of the upper neck). I don't buy into the idea of graduating the tension down as you go towards the bass (e.g. in the list below the 3rd course is at 3.4Kg whereas the 7th course is only at 2.6 Kg). The octave strings need to be slacker than the basses by about 0.3 Kg- 0.5 Kg. I also find it useful to pull the bass strings up a bit so that there is a slight angle with the octave strings when you pluck down with the thumb, but that is another issue. Obviously each instrument has its own characteristics (hardness of top, barring, etc) and these tensions can only be a guideline. It is not easy to experiment with just one course at the 'right' tension as the overall bridge tension is going to have any effect on how each course feels and how the instruments reacts, but it can at least give you some idea without going to too much expense. The other thing to take into account is where you play with the right-hand. If it's very close to the bridge then you can get away with less tension.
