Yeah, you can think of it as a percentage. The min is 1 and the max is 99. It could be 100, but I don't trust my mostly untested side project that much, so I cut it off at 99 :)

The base confidence score is determined based on how many words a guess technically could be, that's here - https://github.com/mattruzicka/wordle_decoder/blob/0bfd7eaac...

Then, I sort of just willy nilly add/subtract from that based on the "intrinsic" score of the word which is computed here - https://github.com/mattruzicka/wordle_decoder/blob/0bfd7eaac... and then the "contextualized" score AKA how well it works with other words, which is computed here - https://github.com/mattruzicka/wordle_decoder/blob/0bfd7eaac...
