>>You only notice because you see the first 4 horses, they are the only horses that >>have odds posted on the screen. You don\'t notice the horses further back. There >>are many instances where the odds change for horses farther back in the field.
We have pari-mutual betting. Any time the odds change on one horse, the odds must change on all horses.
Yes, a horse at 50-1 isn\'t going to show much of a change on the tote in a big pool. But it does in an average track pool daily. If we displayed odds in single digits rather than the grossly averaged way we do now, big moves at the last minute would be clearly more apparent, when a horse drops from 1.80 to 1.50 (a huge move in a big pool)
If we stopped betting five minutes to post, the odds would still change the exact same way they do now down to post time. We are using different computer systems to funnel multiple local pools, ADW pools, international pool, etc., into the final odds construction.
Yes, I know there have been documented incidences of past-posting.
