I can answer that. ;)

Stats since 2002-12-14
Scores        : 0.7 18 45
Total Messages: 4237
SA Caught     : 4116    (97.1 %)
Razor Caught  : 3189    (75.3 %)
Razor Not SA  : 1       (0.0 %)
Razor Cause SA: 90      (2.1 %)

So for me at least, 2.1% of my SA catches are caused by Razor's help.
The other 95% are caught by SA alone.  And yes, that number is dropping
over time as spammers change how they send their stuff.  That's why
there's always new versions of SA in development. It's a cat and mouse
game. ;)

 of course match nothing.   :-)
