Sometimes I’ll play all day long on a Saturday, and after several hours I’ll become competitive with players who have 2K or so more PP than me. The next day, I’ll play again and my PP will spike as I win a number of matches. At this point I’ll be pretty competitive with virtually everyone I run into except for the small number of really skilled players online at a given time.
Then the work week begins, and I barely have time to play at all. Sometimes 3-4 days will pass where I don’t touch the game. When I eventually log on, I can only compete with new players unless I dedicate several hours to playing. I get totally creamed by the same people who I was literally destroying just the previous weekend, it’s really bizarre.
