You don't need to tighten it to a location, just a torque. With the wrench in one hand and the opposition crank arm in the other, you should be tightening until it becomes rather difficult to get the bolt any tighter. This requires a little muscle, but not blowing a vein in your forehead. About the equivalent of lifting 30 pounds in each fist. You really have to either wimp out early or be trying to prove something to get it wrong.
For this last comment, you are replying to the wrong person, but writing it as if you are replying to me. Please stop doing that.
For the first comment: I don't see a clear story that 115.5 is the correct length. And if it is, my main point is that a few mm difference might not be significant for the OP once it's all installed and torqued. One thing we don't know is how good the Campy cup/Dura spindle installation was: Q, Chainline, symmetry, chain stay clearance, clean chain running. This is where I would do trial assemblies, to make sure (if it was me) that my new installation is not worse than my original installation.
Honestly, I don't think we even have clear evidence that the chainset is Super Record or something older. And if the cups were for Super Record, the cup is made for 3/16" balls, and hence ¼" balls are not going to fit the races right, and the lateral relationship between even a correct spindle and the cups (hence the frame) will not be right.
