Well firstly, thanks for all the kind welcomes!
And thankyou to John, those weights seem to make sense based on the other weights I have found and thats good enough for me. I did know about the platform 5 book but just couldn't get hold of it, it wasn't at the University's library and wikipedia didnt help either. So thankyou all once again. I wish I could acknowledge all of you in my dissertation.
Regards,
Geoff
