I got an S on summer wars with a slider break in the middle, giving me 45 pp. When playing it again I get a higher combo but drop some notes at the end resulting in an A and a higher score but I only got 42 pp. I get that getting an "S" is probably worth pp on its own which is why this happened but the game shouldn't make me lose pp just because I get a higher score with an A grade....
