2:06.30 for the Standard is stupid.
Someone should tell the Japanese Federation the reigning Olympic AND World Champion marathoner Stephen Kiprotich has a best of 2:07.20
The Olympic/Worlds are run in the summer often in hot less than ideal conditions with no pacers (unless 1 of a countries 3 runners sacrifice them self for a teammate who excels in fast paced races, but that almost never happens as everyone is for themselves in the global marathons).
Getting more runners under 2:06.30 is a good goal, but Japan should send 3 marathoners regardless as things can happen especially in hot weather.
