I appreciate you taking the time to look into the material I've provided you.

Anyway, I noticed that https://lb.ua/news/2010/01/14/19793_nalivaychenko_nazval_kolichestvo_zh.html says 10 million, while https://hexbear.net/post/20004 links to it and claims it says 4 million. I guess the wayback machine should be checked.

That's odd. Good catch!
