Sorry, Peter, that's simply wrong.  Relative fitness is fitness relative 
to a reference genotype (you can choose any one you like - any 
difference gets removed throught normalisation).

The only place where a relative's fitness enters is through the 
contribution to it from the altruistic actor - i.e. b in Hamilton's rule.
