It's not the case that the GRG is only trying to have one man on WSRL. It has to do with the fact that the current list of oldest living people shows the OLDEST people (112+) and unfortunately most men die before their 112th birthday. In the case of Mr Núñez-Olivera, it proved difficult to validate him. The last pieces of the puzzle were sent in AFTER his death. In the case of Mr Gerneth, he chooses privacy over a title. In other words, the GRG has not received any documentation validating his age yet. Therefore, he is not on the WSRL.
