Thats OK Id rather see it put to use than gathering dust ...Its not in mint condition but it still works ...and yes I am a good bloke contrary to popular belief hahaha
Ive just dug out the book doc (its 26 years old ...fark how time gets away) the table in the pricing chapter is actually "weight advantage.......odds"

eg
Advan.....Odds

.5kg.......10/9 on
1kg.........5/4on
1.5kg.......6/4on
etc etc

Of course the Kg advantage can be converted into lengths and fractions of lengths ...but Im not sure if thats what you want ...let me know and well see how we go ...I really dont mind posting stuff from the book Its no trouble I spend 75% of my life in front of the computer ... be happy to help
