Ah, gee, there's the link to the spreadsheet and over there is the D'Addario pdf that has all the unit weights - it's all open for exploration!
That said, a few observations...
1) Standard string sets seem to be based on old formulas that made sense a long time ago when all basses has small neck radiuses and had only standard tunings, and the string materials were not as developed as they are today. Look into almost any commercial sets and you will find that the D and A strings have way higher tensions than the G, and especially the E. Add a fifth string B to that, and the tension gap gets even more lopsided. That's why so many people have trouble finding a B that finds and sounds right.
2) The lower you tune, the more one find that the lower pitched strings are the problem. Especially on 35" and less scale length if you go for really fat diameters around B0 and below there is so little harmonic content and intonation, and spurious inharmonics further up the neck on the fat strings become readily apparent.
3) When you start tuning lower and lower and you want some tonal and feel continuity across the entire string set, it really begins to make sense to make your own balanced-tension sets. And since the lowest-pitched strings of a set are often dull and have all those intonation and inharmonic problems, it seems like finding a compromise low string that speaks well but may seem a little floppier than you like is the way to go.
Then, build the rest of the set around its actual tension. Then an odd thing happens. As you adjust to all the strings having about the same tension that low B or whatever no longer seems like the odd one out, no longer seems floppy, or tonally odd-man-out, and your hand technique acts the same with each string.
So for lower, or extended range tunings, whether you like really heavy strings or fairly light ones, if you build more balanced sets based around the lowest string in the set, then things begin to work better.
Anyway, that's from a few years of alternate tunings and string experimentation, and that's what's worked best for me tonally and feelwise - it may get you where you want to be : }
