Aside from the fact p2pool's 90 day "luck" is at 88.5%, and 30 day "luck" is at 57.1%. Aside from that, yes, it's great.
is there anywhere a graph about the luck of p2pool from the last 90 days?
TIA
Please note that if you choose a pool based on its past luck you don't understand Bitcoin mining. You probably should learn more about how mining works before choosing a pool (I would advise Bitminter or Ozcoin until you understand why you would earn more with p2pool long-term)
