Then there is something else I am not understanding. According to the PPLNS stats on my pool, My last shift is 0 blocks, 527 shares, with a 0.00000000 per-share rate and a 0.00000000 reward. Each time a new shift is started, the number of blocks increases, and the per share rate increases as well. In about 1 hour, the same shift will result in about 1 - 2 blocks, and a per share rate of 0.00000002. In about 6 hours time, it will be about 5 - 6 blocks, with a per-share rate of 0.00000004 to 0.00000005. So how and why does this increase when I am on a different shift? Also, how will I know if I have found a block?
