Anyone can calculate the difference in total reported deaths daily regardless of what date they were attributed to. This was discussed at length previously. Maybe even in this thread.
What difference does it make to us now how the summer numbers were reported?
Because they are still reported that way now.
And it is not as easy as you claim to compare FL to other states on an apples to apples basis because they still report their death numbers in bulk batches ~1/wk. So they'll jump up one day and then increase by 1 or 2 the rest of the week.
It matters because I often see posts like the below that show how "FL is so great because only 1 person died in the last day". Generally, that either means (1) they are comparing deaths that occurred and reported in the past day with deaths that were just reported in the past day, or (2) they are picking a day that FL did not batch report deaths, rather than looking at something like a 14 day rolling average.
