How exactly would you define “Domestic Level”?

For me, this is relatively simple.
Ready for the top 10 in the world is world level.
Otherwise you're still domestic level.
But maybe that's because I'm British. And maybe more pertinently, I make my own rankings (independently of the corrupt ones we see publushed).
That might change if you're Cuban, Anerican, Mexican (generally above Brits) or some other nation (maybe above or below).
