Kevin, Comyt, and Vlad very rarely spar anymore. That leaves Prime and I next, both of whom only have 43k... That's less than half of what Sarah has.
By that math, I don't see anyone even coming even close to Sarah for at least 6 years unless one of those three gets very active or Shan comes back.

Xenthic and Andrew don't play. That leaves Michael at 694k. He could probably get 1m in 2 years if he tried or cared.

It's pretty clear by those numbers that this isn't something that's expected to happen often... And even if it was, I think these two deserve something for being the first and doing it so quickly. Sarah started in 2012 and was a PKer for months before she started sparring. Anyu started when, 2014?
