Well, I've worked out a table of value prices for each predicted margin in the AFL. They are not totally exact, but I think they're close enough to give you a good rough guide. Thanks again to Mo for the formula which I've based this on. Haven't done it all in a spreadsheet for you Benny, but this should be some help.
