That is correct about Art atwood.
But, Darrem beating Rhul is a pure joke.
Joke or not, Darrem has done it (more than once). Charles beat him at the Maximus Pro in 2003 and has placed higher than Ruhl at the Olympia twice (2005, 2007).
Granted, Ruhl was as smooth as a baby's backside at those Olympias (especially 2005). But that's Ruhl's issue, not that of Charles.
