Chen is going with the theoretical and ignoring what really happens
in a contest.
If you know the exchange is a serial number and you receive
TOO QWE 123
Do you really need a repeat? Your brain has done its own error
detecting, because it knows what should be coming and recognizes it.
On the other hand, if you receive TOOAQWEAQWE, what is the serial
number? True, a really experienced operator can pull it out mentally,
but lots of newer contesters can not, and a request for a repeat will
surely follow.
USOS is a clever invention. Please let it do its job by eliminating
dashes in the exchange.
