I don't think the rule should change, we have the option to submit new testcases. Only because I started late, and didn't had much time, I didn't submitted the extra cases I made.

I really think that all of us should post new testcases as much as possible to avoid this.

You might add a rule stating that the public round (not private round) code must pass all possible testcases(even those who are not in the ini), in other words, the code must comply with the rules of the assignment and not with the ini.
