I do not claim to be an authority here, but maybe we need to dig a little deeper. My understanding is that in a closed loop system, regardless of how many cables there are, the tension measured anywhere is the tension of the whole system. The tension on the bellcrank is not at issue, it's how much stress there is on the cable. One exception, if you have bellcranks that are unequal length then the cable tension will actually read differently depending on whether you're looking at the cable on the short legs or the long legs. Aileron cables with a carrythrough cable could be like this. The idea of hanging the weight is correct, but it doesn't matter if you anchor one end and hang a 100 lb weight on the other or a 50 lb weight on each end, the tension is the same. I think.
