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！
