No kidding.
1) The study is pre delta. It’s a study of numbers created by a virus that no longer exists, delta being almost universal now.
2) Wrong attribution of admission/death is not going to fly. Excess Deaths have been rising sharply for about 2 weeks, which means 3-4 weeks prior to those 2 weeks (it takes 3-4 weeks for All Causes death data to accumulate) So right about 1 August deaths started rising. Deaths of all causes. And that happens to coincide with the timing of the Covid death ramp now underway.
