You're right, Jason. I'm sorry about that. I agreed to go back to active cases from three weeks ago as a fair method of determining mortality rate. It was an unintentional gaffe. I should have just looked at my spreadsheet instead of trying to do the calcs manually.
Look, let's just reset and start over. I'll walk this through step by step.
Here's the data source I'll be using, Texas only.

1. As of yesterday, 7/19, we had
3,948 deaths from COVID-19.
2. Assuming the disease runs its course in three weeks, we need the positive tests number for 6/28. That number is
148,728 positive tests.
3. How do we determine
how many actually caught COVID-19, but never bothered to go get an official test? There's a lot of arguing back and forth out there as to what that number might be. But let's stay super conservative and go with Dr. Robert Redfield, Director of the CDC. He says 10x.

4. So
the actual number of infections on 6/28 was 1.64M (148,728 * 11)
5. 3,948 deaths on 7/19 divided by 1.64M people infected on 6/28 is an
effective mortality rate (IFR) of .242% for COVID-19 in TexasI don't know where in the world anyone is getting the .5 and .65 IFR numbers you're quoting. But conservatively, in Texas, the mortality rate is at most 2.4x that of the seasonal flu
right now. Our IFR is going down day on day, as it has been since we've been keeping data. (For instance, on June 24th, the number was .3. It was .4 on May 29th and .5 on May 16th). I think it's very reasonable to expect it to continue this decline as we continue forward.
Again, let me know if you want to see the spreadsheet.
