I may have been reading the Block Shares graph on the Blocks page incorrectly.

So if the Actual (orange line) and Average (green line) are below the Expected (blue line), does it mean:
1. it took us less time (less shares) to find blocks OR
2. we found less blocks

In the last hour we had a 108% luck (unlucky), yet if the first case above was true, it would mean we have found blocks quicker than expected, right? However, the Block Overview below shows the opposite and makes me think the second case is true.

Can anyone confirm or even elaborate further?
