That sounds about right. According to organofcorti's blog, our average time to find a block over the last 3 weeks (Jan 04-24 inclusive) is 1.2x, 1.2x and 1.42x the expected value, which is 78.5%. It's been a bad start to the year.
Thank you for pointing me to that. What is interesting to note is that recently all major evaluated pools ran into bad luck. Looking back around one year, we see how bad luck and good luck pools were par - which is what one would expect. Today, all of the pools are significantly unlucky (over 1.2). How probable it can be that a set of pools worth 50PH are unlucky - individually and as a set? Variance aside, there has been a monotonic down-trend in the luck over the past year - unless I knew better I'd suspect either a systematic error in how the statistics are collected or something very fishy is going on. I'll try to get some feedback on that from organofcorti before starting conspiracy.

"all" pools ... no.
