I'm with you Lucko, it irritates me that we are essentially penalized for an error. even if a block gets orphaned, our DGM estimates shouldn't drop as they would have with a paid block.
Just to comment this a bit. Real orphaned needs to drop DGM average. But error shouldn't. DMG pays more then pool makes so orphaned fix that. Alternative you can also have higer fees to negate that. But DMG itself plans to count in orphaned and calculate payments accordingly... So that is OK as long it is not an error.
