also 'obvious' category -
'Unknowns' (first time starters without Super(debut) Trainers, certain layoff situations, etc...)
- 'unknown' that is cold 'dead' or hot 'live' on the board may correlate to performance, sometimes more than pedigrree, workout, trainer stat,, etc... models models that we have available...
correlated
also, occasionally see more established ('
known') horses whose odds on the board stand in significant distance from their projected performance models.
- maybe this is exactly the opportunity which we've been waiting for! and overlay, or an underlay... Time to Wager!!
- and/or maybe this horse has a 'narrative' (a fan favorite, an obvious trip, etc...) that is being overbet...
- and/or maybe this horse has some inside informatiion that is pertinent to today's performance, while not evident in past performance
When the odds 'don't make sense' you want to do everything you can to be able to distinguish overlays from inside-info. Addiing some models, and/or blending today's projected odds into the model are ways to overcome this.
