How did you determine these numerical values? Without a proper explanation we can only label these as arbitrary.
Aside from that I agree with the list for the most part. I don't really agree with Randy Couture or BJ Penn being on there since they are hugely overrated fighters who have been gifted many title fights. Same goes with Frank Mir (Who I'm somewhat surprised isn't on this list.)
The person that really shocks me is Yuki Kondo.
This All-Time ranking is based on the score that we calculate (All Time Total).
There is formula and a detailed explanation on All Time Rankings formula
You can also see a complete list (500+ fighters) on All Time Rankings List
There is much more there, but if you want I can copy some of that here.
It is just difficult to put a big table into a text like this (and you cannot sort).
Yuki Kondo was ranked #1 in LHW from 1997-1998.
From 1996 to 2001 he was always ranked top 10 LHW.
And that includes his time in UFC.
