Hi - I posted this in the "newbie" forum, but didn't get any responses, so I thought I'd try again here. (sorry for the double post) -- Does anyone have any info as to where the data for public betting percentages comes from? Are the percentages posted by sites like sbrodds and line services like Dons Bests from a single source, or does each site/service compile that information on their own? Do these percentages include data from all books, or just online books? And why do the books have any incentive to share this data in the first place? Sorry if this is a "noob" question, but I'm just trying to get a sense of how accurate these percentages really are.
Thanks.
