So, when I asked "why so few by so little" just now, it was regarding FRANCE.
But since you took it a different route, whenever I asked the question before, it was always regarding the population of non-Africans, comparing the smaller quality and smaller quantity of their very best results, with the much larger quality and quantity coming out of tiny nations in East Africa. When you consider the population of East Africa compared to the rest of the world, these discrepancies become even larger.
I've been accused of skewing the statistics to favor my conclusions, but if anything, grouping all non-Africans together, and picking the 5 best from this large population, hugely favors non-Africans, the group with consistently lower quality and quantity measures, over East Africans, despite 15-30 times the population.
When you look at the top-95 (data from Jan. 2018, so missing some new entries from Dubai 2018, 2019 and Berlin 2018), there were only 36 non-African women faster than 2:22:56. I considered 36 rather small, especially compared to the 59 from Kenya (29) + Ethiopia (30). These 36 women come from 12 different countries:
11 from Japan (top-5 average 2:20:24)
6 from Russia (top-5 average 2:20:53)
5 from China (top-5 average 2:21:02)
4 from USA (average 2:21:06)
2 from Germany (average 2:20:32)
2 from Romania (average 2:22:12)
1 from Britain, Belarus, Ukraine, Ireland, Australia, Latvia
0 from France
Compare this to:
29 from Kenya (top-5 average 2:18:45)
30 from Ethiopia (top-5 average 2:19:12)
(these numbers would get better with the inclusion of Dubai 2018, 2019 and Berlin 2018)
While China and Russia have a reputation for doping, Japan, with the highest quality/quantity combination, does not. Once again, Russia, by far the most doping country by nearly every measure, was not better than Japan, generally not considered to be dopers.
When you ask "why so large", we know that Russians were taking cocktails with steroids and male hormones, which I've conceded would have a larger effect on women, than men. I suspect it is also the case with women from Belarus, Ukraine, and China, that they were taking drug cocktails with male hormones.
When you ask "why so large", with respect to the women's marathon, I also addressed this in my analysis. There, I computed a 1990 reference of 2:22:56, something I considered quite weak, given that #3 Rosa Mota (2:03:29) was 2 minutes slower than Joan Benoit and Ingrid Kristiansen, and #5 Grete Waitz was 1 minute 30 slower than #3, and more generally, the relative immaturity of women's distance events before Zola Budd, Grete Waitz, Ingrid Kristiansen, and Joan Benoit.
If you consider (like I do) that my 1990 reference is weak for the best elite women marathoners, it becomes even more surprising that only 36 non-African women could beat it, in nearly three decades of EPO availability, given the scientific promise of 3-4 minutes advantage.
When you ask "why so many", we know:
- Russia was doping their women with drug cocktails.
- Many people, athletes, coaches, managers, and fans, believe doping is necessary to run fast -- which includes top athletes. We should expect some prevalence at the top, even in a scenario where belief is strong, but effect is not.
