Most useful is the ability to search results with toggles for odds ranges. When a model is developed that shows a positive ROI, rather than betting on it with both hands, the researcher is well advised to re-run the same data with the odds range set to a more reasonable range to see if the positive ROI still exists. That is, with filters set in a given pattern, an ROI that shows up when "any odds" are searched may change substantially when "only odds <= 10-1" are considered. Especially with small samples.

Traynor,
Another technique that I like is adding some randomness. If a horse won by a nostril hair and pays $68 that should have different value than if the horse won by 12 lengths.
And sometimes thread drift is a good thing.
