So earlier I played a hard song from a while ago just to beat it for old times sake, I beat it and I gained 1 pp. Then I went and I played one of my top ranks A on an insane and I missed the last 3 notes which dropped me to a B, but I beat my old score. It registered before I could retry or realize what had happened. THen I looked at my pp again and saw that it had fallen by 1. I have never seen that happen and I heard that you can't lose pp. I know pp is calculated by accuracy and score, but do you really lose pp for messing up your earlier ranks?? Also is there a way to remove the score . I know their probably isnt though. But yeah, im kinda interested in knowing if you can lose pp since then i will be more careful
