The data is calculable on how long it takes to move up- max movement is 24 points per game. Someone who is a true 1% player who is somehow in tier 5 is probably going to consistently get 24 point upticks. 5 games for 96 point game in PSR, 50 games for 960 point gain. The higher they go of course the slower they would gain as they are less likely to get the 24 point increase games and in some cases as they face better opposition they will have games they go down. At some point they'll hit their cap either based on their PSR up and down games balancing out or because they hit the true PSR cap of 5000.
By definition 99% of us aren't as good as a true 1% player - we're going to go up slower on average even starting in tier 5 and we'll hit our equilibrium point at a much lower PSR value. But you can pick whatever number you want to use for average PSR gain per match from a tier 5 start to calculate how long until they hit that players equilibrium point.
Planning for regular reseeding ensures the infrastructure is in place for unplanned reseeding. PGI reseeded the global population once last year and reseeded the global inactive population a second time. Changes in Match Score calculations (which are planned) will doubtlessly cause some shuffling as well.
Placement matches and reseeding are a control against low sample size. People who play 10,000 matches a year aren't going to see an impact, and admittedly that's a majority of posters on these boards, but it's not typical of any online game's population.
