Booking classes on seatcounter

Hi,
not needing it that often I am to tightfisted to spend money on expertflyer and have tried using seatcounter instead for finding out how full my flights might be. I am not after a certain reward fare class, just curious...
Now I noticed that the fare classes on seatcounter don't quite match what the fare code list on v-flyer describes. For example W for 'Full P E' is blank while there is a figure for R, a class that VS supposedly does not use? BTW: I used VS005 on 20/10/08 to check.
Has any one else noticed that and maybe has an appropriate list of codes or better tool?
Cheers,
Mike
