So this means highest ranked person from that country?
I don't understand what you mean.
But the qualifing will go as follows:
There are just 8 qualifing groups, winner of each group goes to Olympics, most group will have 2 players, 1 or 2 groupes will have 3 players.
Then 16 players are at the Olympics, 4 groupes with each 4 players in it.
Number 1 and 2 advance to next RR round, from that RR round also the number 1 and 2 advance to SF's.
