我看一下官網的說明是這樣 https://osu.ppy.sh/wiki/FAQ#Grades osu! Standard Normal grades SS = 100% Accuracy S = Over 90% 300s, less than 1% 50s and no misses. A = Over 80% 300s and no misses OR over 90% 300s. B = Over 70% 300s and no misses OR over 80% 300s. C = Over 60% 300s. D = Anything else. 但我剛剛打了一個 90% 的卻只有 B 如圖：https://i.imgur.com/Db5MSkP.png 甚至之前也有達到 "Over 80% 300s and no misses" 想請問為什麼都拿不到 A 呢？！還少了什麼條件嗎？ （仔細看一下好像我拿到的分數都少了一點呢） 謝謝！
