Just a comment about deaths reported over weekends... Some states require death certificates to be processed through the state health departments which are closed on weekends. It may be that the deaths occur earlier, but the paperwork needs to catch up. Happened when my mom died on a Friday evening last year. We needed to bury her in another state and couldn’t start that process until the flowing Monday.
Cause of death will be on the death certificate, so won’t be official until it’s issued. This is just my guess as to why the numbers fluctuate so much during and right after weekends.
It does seems like it may be some sort of bureaucratic SNAFU.
