Not sure where you got your numbers, not from this site. I went to the Texas site that is linked from worldmeters. In the last week, there were three days when total reported cases exceeded ANY day previously in Texas. As I mentioned earlier after looking more closely at county data that you can conclude that this spike may be a result of additional testing in high risk areas, but it IS a spike. Still, your numbers are simply wrong.

May 15th: 1347
May 16th: 1801
May 17th: 785
May 18th: 909
So as of today, the rolling five day average is 1,258, which is higher than all but two SINGLE DAY counts in Texas prior to this uptick.
