STALE leads in the previous complete six-turn benchmark

These game-length figures come from the previous complete opener benchmark against its 2,354-answer snapshot, ranked by average guesses among games solved within six. Its answer snapshot and continuation policy are separate from today's solver recommendations.

The same solver played from both openers. STALE has the lower average in games solved within six: 3.57 guesses to 3.73 for ADIEU.

Looking only at the opening row, STALE has higher entropy (5.74 bits versus 4.89). That describes first-guess separation, not the full solve on its own.

Against 1,859 past Wordle answers, STALE left the smaller first-guess group on 61% of dates; ADIEU did so on 39%, with the rest tied.

A fully gray row is rarer with ADIEU: it happens 7.0% of the time, against 9.7% for STALE.

ADIEU is not on the possible-answer list, so it cannot solve the game on turn one here. It can still be a useful guess.
