So I uninstalled my Osu! as a part of reformatting my PC, then up til 2 days ago, i reinstalled it and saw that my account is still intact with my rating now in 6-digits, and my accuracy rate is at 96.98. I played a couple maps, then when i got an S on a map that i once got A on, i rested a couple minutes. Then, to my surprise, my accuracy rate DROPPED by 3 (from 96, it went down to just 93). I actually expected it to go higher, even if only in decimals. I read on the Help section regarding the rating system, but this is completely unheard of, even if it's only to me. Are there any factors which could've led to the decline in my ranking and hit rate?
