I believe I made a comment to one of your other posts about this. My earnings are 1/4 what they were with the same metrics. But not just this week. Ever since the newest changes were announced, I think. I don't follow my stats as closely as you do, so I may be wrong about timing, but it's been going on at least a month for me.

Essentially, Medium has cut our wages.

EDIT: Actually, my metrics are generally better than before. But my earnings are way the hell down.
