The comparisons between aging factors might reveal if the scale is linear or follows some curve or is somewhat exponential, but maybe it won't. From what I've heard there's really not a great deal of difference between the life expectancy of people on the 12 (+ levels or even between them vs. Elaida level sisters, while there is about 3 times that gap between Elaida and Daigian. I don't know what you math-heads can make out of just that, though...
This brings up an interesting idea that Elaida and could be far closer to Lanfear than to Daigian.
And good to get at least the hints of conformation that the bell curve is the same. Excellent to know the Wise Ones are a good representation of that Bell Curve.
Either way, seeing all or some of this in the encyclopedia will be fun.
Hmmm... not sure the WO are totally representative, they had more than the 62.5% covered by AS, I guess especially in the lower levels. They might not have been that much luckier with the highest ones, since testing isn't compulsory. They test women who come to them and they deem WO potential. They only take without questions all sparkers.
