I used to use “stare” or “stale” as the starting guess when I played Wordle, thinking you’d want to start off with the most common letters, like R-S-T-L-N-E from Wheel of Fortune.
Suboptimal - likely. There is some utility: a green letter is more useful than a yellow. Checking for a in two locations when a is a very commonly used letter is __useful__. Still likely much more useful to check for the presence of a fifth letter than a chance at knowing more precisely the location of an a.
