Good point and depending on country of nationality, the odds can in fact be pretty good.
Are the odds still good?
Thanks for posting it. It's super-interesting. I always suspected the chance for my country (Australia) was _reasonably_ good. This bears that out. In fact it might even be higher (5%) than I'd expected.
That being said I tried like 6-8 times and never won. But that's not too surprising even at 1 in 20.
In fact I think I've only ever met one person who had won this. As it happened he was from Russia.
Oceania (Australia, New Zealand and some other islands) happens to have few applicants relative to its regional quota.
If it is that, then it's a terrible name.
Selecting by country of birth prevents those shenanigans.
