So lately ever since I entered the 210-190k rank range nearly every time I've improved a highscore on a map, (+500k score, +0.03 acc or something like that) I've always lost rank. Is there a guideline I can follow so I know when to quit before I finish a beatmap and change my score: like I should try to 2x my combo (even though I would still lose rank if I 3x my combo) and atleast improve acc by .05?
