I think this could be a problem of numbers. If you keep using percentages, you will run into issues because that doesn't seem to be how actual strength works per se. If you think of Lanfear, at the apex of the female strength rankings as having access to 100,000 saidar, while Elaida would only have access to 10,000 saidar, I think it is easier to appreciate the gulf between them, but if you look at their rankings and try to derive their actual strength from their relative positions on a chart dedicated to the rough positions of Aes Sedai, you could get thrown off from the fact that Lanfear is on that list at all. I don't think percentages are safe to use to try and find actual numbers when we are missing so much information.

We are basically shoe-horning outliers onto an imprecise scale, and then getting thrown off because those outliers don't reflect a smooth progression.
