Ditto. You can fix it:

const d = JSON.parse(localStorage.getItem("nyt-wordle-statistics"))

console.log(d)

d.currentStreak = // whatever your streak was

d.gamesPlayed = d.gamesPlayed - 1

d.gamesWon = d.gamesWon - 1

d.guesses["4"] = d.guesses["4"] - 1 // subtract the last game

localStorage.setItem("nyt-wordle-statistics", JSON.stringify(d))
