@Amoulier Both your deadlines were on the long side, so there were likely a number of other miners with DL's close to yours. This significantly dilutes your share of the 60% for the current round. Your historic average is pretty low - of the 40% paid to that side of the pool you're getting just over 2 burst. So given the time on your forged blocks and historic shares, 600 or so is not unexpected or unreasonable.
that was what I thought ... But needed to be sure of it. Thanks for the responses!
