2) There have been no backend changes for ScryptGuild. There have been no changes to the backends period in the last 9 months. 6 of those months were positive on luck. The last 2 were not. The 9th month isn't available since luck only started being tracked across multiple difficulties 8 months ago (prior to that it only showed the most recent shifts of the current difficulty).
eleuthria, you should just eliminate the luck graph on the site entirely. Even though the metric is measurable, it cannot be acted upon, so, in this instance, the measurement is not valuable. And if I have to read the "bad luck" posts for 4 more months (until we are even again), I'm going to kill myself.
P.S. Yes, I do know that the 4 month number is not really the guaranteed length of time it will take until the variances work themselves out - it was a joke.
Bad luck graph or not. It's pretty fucking obvious when there's a continual stream of >6 blocks found per shift when historically it's been >9.
