I got the same numbers on three sites including the CDC which I linked below....and "people being tested multiple times" like for travel or work and testing negative multiple times should decrease the positivity percentage not increase it....yes some who are positive might test positive a few times but those tests done for travel far outweigh those people,
CDC daily positive covid case chart link...and using your link the 7 day average daily case number as of yesterday is 55,423 (Worldometer)
