We've had a pretty unlucky run over the last 24h - check it out for yourself
http://simplevert.com/blocksI ran the numbers last night and it looked like this
24 hour luck avg - 140% work completed of expected (40% less lucky than average during this time period)
48 hour luck avg - 100% luck
Just curious why you use a non-linear function of round shares for your stats (luck %). A simple % of expected shares is much easier on the brain if you want to guestimate average pool performance over time with a look at the stats page.
