they look at all 5 EG champions in the various category...if 1 or more are not qualified through the OQR, the highest in the world ranking among those champions will be awarded the quota...
if all the champions are qualified via OQR, then they look at all the silver medallists from the EG (with the same criteria, looking for the best in the WR)...
if also all the silver medallists are qualified via OQR, finally they look at the bronze medallists (always the same criteria, the best in the WR gets the spot)...
if all the medallists are already qualified, then the spot(s) are reallocated through the global OQR...
therefore, as we wrote before, everything will be known only by next month of April 2020 at the end of the OQR...
