Good point! In cumulative deaths per million:

                  US   AUS  delta
    2022-01-01  2477    87   2360
    2022-02-01  2673   141   2532
    2022-03-01  2852   204   2648
    2022-04-01  2948   247   2701

I didn't look closely at the graph and I misread the recent apparent spike, which I agree with you is likely some kind of correction.

I'm sorry I can't go back and edit my comment!
