The summary should include top 2 most frequent burst sizes, but there is a bug in finding the top-2. During the scan of burst size counts, the top-2 can change only if top-1 also changes. Added logic to update the top-2 if current burst size is larger than existing top-2, but smaller than existing top-1.
