Are you sure about that? Then why is difficulty stuck so high for days at 21 when practically no one is mining?
Yes. The dev clearly stated that KGW does not begin until block 67000. What you are describing is exactly what KGW is designed to counteract. From what I understand, KGW adjusts the diff after each block. With it we should never be stuck with a huge diff and low network hash for more than one block.
