Much thanks for the explanation!
I did not realize that the previous rounds work was used in the calculation. Log term will be just fine. Up till now I did not have a dedicated rig pointing at this pool, but I now have one dedicated to this pool. Will add more as time and $ permits, but leasing a few and dedicating a few rigs seems to be a good mix of btc luck for me.
yep, if you shut off your rigs, I believe you'll continue to get some payouts even for blocks that you submit no shares... not sure how long before the DGM payouts become zero again.. I'll leave that for those who are smarter than I to explain.
