How EXFIL performs as a guess
Wordle accepts EXFIL as a guess, but the solver does not list it as a possible answer.
Played as an opener, it lands at least one colored tile in 76.6% of games, misses completely in 23.4%, and leaves about 299 possible answers on average.
In the previous complete opener benchmark, it ranks #13,593 of 14,855 openers, averaging 3.87 guesses in games solved within six turns.

First-turn measures
All four describe EXFIL used as an opening guess. Entropy is the same idea as “avg ruled out” on a log scale: a higher number means the guess splits the possible answers into more, smaller groups.

Optimal play
Opening with EXFIL, a proven-optimal strategy averages 3.87 guesses — rank #13,225 of 14,855 legal openers. The best proven opener, TARSE, averages 3.55.
In hard mode it averages 3.98 guesses at best — rank #5,821 of the 7,453 openers that can still guarantee a solve within six guesses.
Our six-turn simulation says 3.87 — at or below the proven-optimal 3.87 only because the two figures score different answer lists.
These figures come from exhaustive game-tree search and are exact for the NYT lists of July 2023 (3,158 answers) — not the site's working answer pool.
