To solve this problem, I suggest we shave one minute off each of the seven-minute rounds in the first round and give those minutes to the independent round. If they're present, we do this. If they're not, we don't. Between the first and second rounds, the problem is solved. It doesn't add any time to the meeting—it adds one minute—and we only give that minute each to them if they come.
