I found a very interesting thing about LL ranking and LL (computing) speed.
First, let me list some data:
RankingPlace versus LL speed
the 1st place --- 237 (P90)year/day (from
http://www.teamprimerib.com/rr1/bin/top.php)
the 100th --- 2.136 year/day (not the speed of the ID currently at 100th place, but the speed of the 100th place, based on the data recorded during past 300 days)
the 500th --- 0.510 year/day
the 1000th --- 0.263 year/day
The data show that it is roughly true (but I don't know why) that
Speed(Nth place) = Speed (1st place) / N
Assume this holds OK for any ranking place,
now you can estimate where is the highest ranking you can reach ("theoretically")
