Chrome,

Trust your instincts is all I can add.If you have a shortie prepost,use your own judgement as to whether it is justified to be that short and whether it will firm or drift.As prepost markets for Saturday's races would have to be framed on Thursday to meet printing deadlines,then adjusted again on Friday for the same reason,without any knowledge of final scratchings,track conditions,how could they ever be truly accurate,regardless of who supplies them?

Sportz,can't agree with you there.It's the first 5 lines of betting that win 80% of all races regardless of odds.If you look at it from an odds angle,that's a different set of stats that I don't know.Do you have any figures on % of winners of all races using your theory?
