3.5 is correct. It assumes 52% of population female, and uses RATIOS OF ETHNICITY of each nation!!!! USA is not 100% white for example! And you already know about Germany France Etc. You do need to drop in a few whites from many south American nations, and even a token few from odd nations, but you need to algorithmicaly ADJUST OUT ALL ARABICS called "white" on every nations censuses. Jews call temselves legally non-white, so remove another 1.6% of USA for example. And of course 50% of hispanic (mestizo) falsely calles themselves white ... you need to adjust. eliminating moorish "olive" peoples, and such you get... NO MORE than 4% White Females (generous) and closer to 3.5% Females using 2021 populaiton of World. Its 3.5% ======= 3.5% !!!! Differing values from 3.5% never show thier work and when they do its comical overcounting to make it higher.
