People get pretty upset when there are rounds that are hours long without pay. It literally scares people away from the pool as I've had people complain. When we have a high enough hash rate to tackle doge blocks in under a couple hours I'll do it but now is just unreasonable.
Solution: only mine the extremely profitable doge blocks... say, those that will be over 800,000,000 reward. Sure it might take you a few days to hit one, but the pool will absolutely profit in the end. And switch off doge as soon as a block is found and the next block's reward is lower.
