At least twice a day.

Yes, sure. Also because this, I have to use anonymous submission to
test my code before I am sure it works.

Not really. I was not ready to submit my code at the end.

No. I worked hard to develop my own code but was not satisfied with
it at the end.

Not this time. In most previous contests, I did.

I don't think so. Competition is always overweighted, particularly at
the last minute. Cooperation is very trivial. I also do not see any
cooperation channel practically operable. Maybe, some discussions in
the News Group can be counted as this, but most of them are about
past not future. Originally, I think big push prize may motivate
cooperation. But, it did not happen.
