in your example, you took a block that needed a lot more than on average, so payout was a lot smaller.
True. I based it on the most recent block. Mostly, I am interested in how pay-per-share is determined. Based on the last block it would seem the operator would have lost out. Then there is the risk of unconfirmed blocks being paid out as well.
Not picking at all by the way, just fascinated by how it works.
