Is it normal that when you beat a score in a beatmap, and improve your accuracy, your total accuracy still goes down?...For example my total accuracy was 98.20%, and I had like 95.70% in a beatmap. I managed to beat my highscore in that beatmap and got my accuracy to 96.80%-ish, and yet my total accuracy still dropped to 98.19(it's not a big drop, but I went from 98.60 to 98.20 just coz of beating scores on low accuracy beatmaps, and the accuracy just kept dropping)
