Case Count Mismatch with COVID Tracking Project: WA

[gnguy]

The rt.live site cites The COVID Tracking Project as the source for case data; however, there are a few cases where the data on the COVID Tracking Project do not appear to match the case estimates displayed on rt.live or in the rt.csv file.

Specifically, for Washington State, the rt.csv file lists 202 new cases for April 26th and 342 cases for April 25th. The daily.csv from the COVID tracking project lists the positive cases as stuck at 13,521 from April 25th through April 27th. The increases on either side of this data gap from the COVID tracking project match exactly with the case increases in the rt.csv, but I am not sure where the values for the 26th and 27th came from. Is there documentation around how these numbers were generated, and why they may differ from the COVID Tracking Project results?
