Am I misunderstanding something about the diff adjustments, or is something strange going on? It's jumping from the 150s into the 260s while the network hash rate barely moves. Unless the pool display of network hash rate is off of course.

Edited to add: I understand KGW, but it shouldn't make diff jump around that much if the network hash rate goes from (e.g.) 4.3GH to 4.7GH. Should it?
