Your numbers don't add up, because the last way you said it, you said 20 minutes for the first round, 15 minutes for the second, 10 minutes for the third round, and 10 minutes again for the fourth round, and 20 minutes for the last round; this makes up 75 minutes. The way it was said previously was 20 minutes for the Liberals, 20 minutes for the government, 15 minutes for the Bloc, and 10 minutes for the NDP. This adds up to 65 minutes. So there's a ten-minute discrepancy between the solutions.
