Dak to CeeDee wasn't perfect, even if we allow all "the throw out what we don't like." 9 targets don't meet the league requirements any longer, although there are calculators still online that will allow the use of smaller numbers.
Only Nick Foles has accomplished a perfect passer rating with seven touchdowns thrown. Two quarterbacks have accomplished a perfect passer rating with six touchdowns thrown: Peyton Manning was the first to achieve the record on September 28, 2003 against the New Orleans Saints, while Tom Brady matched the feat on October 21, 2007 against the Miami Dolphins. Thirteen quarterbacks have accomplished a perfect game with only two touchdowns thrown. It is impossible to achieve a perfect game with only one touchdown because of the 10 passing attempt minimum to qualify, combined with the minimum 11.875% touchdown-to-attempted-pass ratio.
This appears to be due to players like Frank Gifford (8 perfect games), LaDainian Tomlinson, Walter Payton, Marcus Allen, and Antwan Randle El. These players come on throw one complete pass covering the required yardages for a TD and are credited with a QBR 158.3. In 5 games Tomlinson was 5 for 5 for 100 yards and 5 TDs.
In 5 games Payton was 6 for 6 for 136 yards and 5 TD , while Allen was 6 for 6 201 yards, and 6 TDs in 5 games.
Randle El went 4 for 4 in four games, 156 with 4 TDs.
They are still in the record book among those who have accomplished the most perfect games in a career.
Throwing out all the older records and players who aren't QBs, and using 158.3 as the standard, these QBs have the most perfect games in a career.
