Does noctie treat the opening any differently when factoring in ratings. I had two very different estimes - higher one (2100) was from an opening line i knew and lower one (1500) I left the opening more quickly but I don't think I played a much worse middle game. I'm closer to 1500. [edit: from your other comment it does look like it takes the opening into account - I'm guessing as some sort of calibration - if you create an account does it use the results from previous games instead?]
Also curios if this could theoretically be applied to historical games as well or does it require noctie to be a participant. I'd love to see an analysis of how player strength has increased over time. [edit: from your other comment it looks like it does require play]
