12th August Weekly pool statistics


I hope everyone is enjoying 4.2 Slush's score method and miner earnings part 1. Please post any comments or questions you have and I'll answer them as best I can.

I hope to have 50BTC.com added to the weekly pool statistics soon. I can only access timestamps and blocks, so actual hashrate has to be estimated on the assumption that luck index = 0 and round length / D = 1.0, but not including one of the larger pools at all is worse than a little inaccuracy.


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

If your pool isn't here and you'd like it to be, comment with  a link to a block history with round lengths and either solve times to the nearest second or a timestamp.

Highlights:
  • Deepbit's hashrate and percentage of network hashrate both dropped this week.
  • Ozcoin, Mt. Red, Bitminter and Itzod again increased their proportion of the network hashrate.
  • P2Pool's luck index and normalised shares per round continue to be better than average, now for the last five weeks (although only slightly better than average this week).
