Whenever I set a new highscore on a map and get better accuracy (on the map) my overall accuracy goes down. The only explanation I can think of is that the new score doesn't replace the old one and instead adds a new score which is lower than my overall accuracy, bringing it down. Does that mean its not worth going back and say, bringing your accuracy from 70% to 90% and to only redo maps if you can get higher or equal accuracy than your overall. Is my theory correct or is it something completely unrelated? Any help is appreciated.
