Hard to Interpret – Data might be incomplete, i.e First Time Starters or Horses with Foreign form. Could also be attributed to field changing distances, lacking recency or trying a new surface for the first time.
Legit/Vulnerable Favorite – OptixPLOT output is either positive or negative on the post time favorite, i.e. pace flow, PLOT/run style mismatch or unfavorable Quadrant/Shape for track/surface/distance.
Stalk/Pounce – No dominant speed or lone closer type, the stalk and pounce will generally be a medium or large square in close proximity to the front-runners.
Off/On Pace Flow – Pace flow favors a particular run style. An off pace flow will be a circle crowded Quadrant 1 with large squares in Quadrants 2 and Quadrant 4. A relatively light Quadrant 1 will reflect a pace flow advantage in favor of early pace types.
