The top three pools' total hashrate is just over 50% of the total network hashrate for the first time in a while, and the network hashrate has dropped, too - along with another increase in difficulty.
Average hashrate:
Average hashrate = Total shares / Total round time
Luck index:
log(% of network blocks solved / % of network hashrate)
Luck index = 0 is average luck
Luck index > 0 is good luck
Luck index < 0 is poor luck
Weekly average round length as a fraction of difficulty:
Average number of shares submitted per round / difficulty
Figure 1: Table of all pools with public data and their various statistics averaged for the last seven days - for smaller pools the average may be more or less than seven days, depending on number of blocks solved for the week.
Figure 2: Chart of network hashrate, hashrate of the largest mining pool, combined hashrates of the three largest mining pools, and a line representing 50% of the network hashrate. Handy if you're worried about 51% attacks.
