The website stat.php page shows Round Shares: 253178, but the json_stats.php page shows "shares_this_round":"202142". Which one is correct? That is a pretty large difference

.
At the top of the page, my shares are listed as 5689. On the Account Details page, they're listed as 6769. In my client, 7077.
Also the JSON stats show a second block was found. The site still shows 1.
