We have almost reached 20TH/s of total hashing power, other 5TH/s are coming this week. Hopefully with better "luck" on the pool we should see payouts coming again starting from this week.
Old accounts are getting less performances because hashing power is no more split evenly across deposits, but it's allocated proportionally to the USD value at the time the deposit has been made. However newer accounts when completed will give their hashing power to old ones. Oldest 10 accounts are also getting a further bonus, in order to speed up completion of oldest accounts.
If P2Pool's bad luck keeps harassing us, I will gradually switch part of the miners somewhere else, however I think it's not a very good idea... P2pool is not broken and it should give the max profit.
Just a couple of thoughts here.
Can you give us an idea based on dates of deposits when we might see this hashing power hit our accounts?
I am also curious what criteria you would assign to p2pool harassing us, it has been operating at less than 100% for 90+ days now. The expected time to block is now over 2 days, and the hashrate is steadily dropping. The flood of miners leaving because of "bad luck" will only make the "bad luck" worse.
