Hi fushar,

We got similar feedback a few times both internally and externally. We are
working on making it better, but we couldn't find a great solution.
Disallowing resubmitting the hidden tests is pretty harsh, and now that we
can avoid it, I wouldn't want to do it. Moreover, having the submissions
associated with a problem instead of with a specific test set makes the
system as a whole simpler to understand, which is important for most users.

We are considering alternatives to try to improve the information on the
scoreboard. In any case, we won't make any of those changes in the middle
of the contest, as they would be basically rule changes and, unless
something is seriously broken, rules should remain the same within a given
tournament.

If you, or anyone else here, have other suggestions, we are open to
considering them.

Best,
Pablo
