Who he's competing against is irrelevant...were comparing King against King.
Agreed. So are you the only one who can't see that the difference between King 2006 and King 2001 is not 5-10 lbs as you say, but more glaring differences:
1) His waist has gotten substantially thicker (at least 3-4 inches).
2) His legs are not as big or cut as they used to be.
3) His conditioning from the rear (his old trademark) is completely shot.
4) His arms have actually gotten worse in shape and size.
5) His calves appear to have gotten smaller.
6) He has lost all of his taper.
7) His belly appears to be permanently bloated (the way Titus used to be when King mocked him at the NOC).

His face appears to have aged 10 years in 5 years.
9) His thick Arabian hair is disappearing.
10) His fanbase has disappeared faster than a Big Mac in front of a post-contest Lee Priest.
In other words, it's not the WEIGHT, it's the AGING of the SHAPE.
We saw the same thing happen with Gaspari, Fux, Sonbaty, Atwood. Once the placings drop...they NEVER return.
