Sundays and Mondays are usually the lowest. So the best thing to do is compare this Sunday's number with the previous Sunday numbers.
4/12 - 1727
4/19 - 1570
4/26 - 1156
5/3 - 1153
5/10 - 750
Hopefully, previous patterns won't repeat with a big gain tomorrow and Tuesday, and this will finally be the beginning of a consistent, long-term drop.
Comparing similar days of the week or using a seven day running average there has been a consistent real 4 week drop.
Re weekend dips:
Take a look at the John’s Hopkins CSSE COVID statistics site. In the US daily new case data there is an obvious 7 day cycle. I don’t know if it’s a quirk of the data tabulation, or social in that people do or don’t go to the hospital more on weekdays or weekends.
A few other Western countries exhibit the same weekly cyclicality.
