Mick73, hope you don't mind us digressing from your theme mate? but it does seem like a good idea.

Marcus25, re Pre-post market, yes has always proved to be a problem as of course different publications have differing markets. I always use WA TAB -FORM. Though I'm told that the Racing Radio pre-post prices have proven to be the most accurate (in terms of closest to actual SP)

But for the purpose of what we were discussing 1st, 2nd, and 3rd favs as at SP would suffice.
