Does anybody have an idea of how the 36th-most all-time rep score has evolved over the life of the site? Really, I am asking about the min rep score to be on the front page of the all-time users page. It seems that, while right now it hovers around 39k, I recall not that long ago it was less than 30k, and I am sure it was a lot less a year ago.
Being on the third page, I noted at the beginning of the summer that the top score on page 3 was about $20k$, which registered because it is the highest point at which user privileges change. It is now $21.7k$. Around that level there are lots of regular users who have acquired points over time, some who seem to be less active, and some who are increasing fast relative to those around them.
You can view top users by reputation at the end for each week/month/year in reputation leagues.
I am not sure to whether the reputation is exactly the same as it was at that time. (I do not know influence of the posts that were deleted since then.)
You can also have a look at snapshots of the relevant page in Internet Archive (a.k.a. Wayback Machine): http://web.archive.org/web/%2A/https://math.stackexchange.com/users?tab=Reputation&filter=all
