Some data points can be observed. Most T1 characters are RR6–7. Obviously, we cannot know whether most of them are players trying the game and quitting at that point, or veteran players’ alts, but the peak is there.
There is a noticeable player peak around RR40, which may indicate many characters being “parked” right after reaching Tier 4.
We can also observe a final peak around levels 80–82, with many characters stuck at those levels. It is striking that the percentage of active RR80 characters is the lowest across the entire RR70+ range. I think this reinforces the idea that they have “reached the endgame,” although it could also mean “I level another character to 80 and then stop playing this one.” I think it is probably a mix of both.
