I am trying to say the human that get sicks was 24xx if he did not get sick
the 2400 is based on games when he was sick and games when he was
not sick.
If we look at games between humans at 2600(performance of more than 2600 when
they are not sick) and humans at 2400 the result will be lower
then the result of games between computers at 2600 and computers at 2400.
