Please note that for the final winner selection, a constraint on the missing/refusal rate will be applied. Solutions with high missing rates may be disqualified, even if other metrics are strong.
What specifically is the high missing rate?
The high missing rate need extra clarification, either as a hard constraint, of fuse into the final metric. As it will significantly impact the strategies of whether to provide a answer, it might be better to extend the competition for 1 or 2 week. Peasonly I do not think It is not a good idea to change the rule at this time point.
