I'm a-little confused over your PPLNS, is it if I stop mining and the total number of shares to complete the block passes Difficulty * 1.25, anything I did before that is unpaid? I only ask as shares I had in block 44278 dont show in recent blocks even tho i had some accepted before powering off for bed
Block 44278 was quite unlucky and shares submited that round exceeded N limit almost two times. Round started 2013-04-22 00:40:55 UTC and ended 2013-04-22 11:04:35 UTC so if you mined just before round started all shares have been likely discarded by the N limit.
