Whats the worst round luck we have ever had? Not that I think we are that close to it but hey maybe we can make the best of it and go for a new record!
Back in march, we've had a 48 hours block, that was intense :-)
Periods of bad luck and periods of good luck alternate. Since good luck is less subject to complaints, we have less messages about those, but we're in a kind of lottery which has no preference for a particular pool, so we'll sure have a period at more than 100% again sooner or later. The key is not to lose patience...

... Oh, and I almost forgot : "Withholding attack !"
