The lead of previous round is carried over to next round. Did you account for that? See the table in the question carefully (or give a search on the forums- this Q has been asked multiple times)

The question is a bit unclear. Actually your solution is calculating lead, in each round. But the correct solution requires you to calculate the cumulative lead after each round.
