Graham,

Fisher without graham, yes.  Fisher without robinson.c, no.  In object 
oriented terms, fisher is a subclass of robinson.  In practical terms, 
fisher is built upon the robinson method.  It takes the robinson result and 
applies a chi-square test to determine the likelihood that the robinson 
result is spam (given the number of tokens used in getting the robinson 
result).  Leastways, as a non-statistician that's how I think it happens.
