I have no idea, maybe when Overeem failed the test they were like "Oh yeah? Well we're taking 2.5 inches of your reach...bitch!"
However, the most obvious and blatant lying was marketing Carwin as 6'5'' even though he's not even 6'2''.
Mir is also probably not 6'3'' cause he was shorter than JDS and maybe an inch taller than Cro Cop.
Cro Cop is also listed at 6'2'' even though he's 6'1'' at most, 6'0'' is more like it. I did meet him once and no way is he 6'2'', I'm 5'10'' and he wasn't that much taller than me.
Also, Jake Ellenberger is listed at 6'0'' just like Jake Shields and well...
