There are legit GrandMasters in the 4500-6000PP Range as well. Like hsien, Red Ranger and filipinoman
Red Ranger is on PSN, on PSN you run into laggy opponents regularly even if it shows green bars, so getting high PP is out of the question. I only really care about BP, and those who say that you just have to play a lot to get high BP, if you want to stay above 20K BP you need to have a good win rate. Good luck getting to A+ rank with a 60% win rate, at this point you need more like a 85% win rate if i’d have to guess.
