Man I don't want to be the one who is always saying "just play for fun and don't care about those stupid pp" because I am not the most active player... But honestly, just play a map to the very end and then look how much pp you got, it may be a good or bad surprise sometimes, but isn't that part of the fun? We don't need everything calculated while playing, there are already lots of numbers on the screen that are often hard to understand for newbies.
