This does not track. Maybe if you took it off of hard mode, but most of us require using hard mode. That reminds me, all your scores are void now. Hard mode requires keeping purple letters in same spot on all subsequent guesses once they show up. I actually think it limits the skill in the game, but I lost that argument (to idiots, but was outnumbered), so I went along to get along.
The word list is larger than 2300, at least for word5, I think. I never checked, as I don't wanna overanalyze and suck the fun out of it, but there is a GitHub I was told by the creator
@Pete Winn , and the lists are there. Feel free to suck out the last bit of fun from it and feed this to your AI.
