Hey, why my point performace decrease? But 2 days ago, I'm played old beatmaps and get top 500 ranks and I get my pp. But yesterday I'm play old beatmaps again and get 500 top ranks again and when i'm submitting score for that beatmaps, why my pp decrease? From 3,256 to 3,120. Can you give me a logic reason for what happened to me? Thanks ^^
