A horse running on Polytrack for the first time will have a Gplus rating based on workout times. These are notoriously unreliable. Unless the horse is trained by a high-percentage synthetic trainer (e.g., Brendan Walsh or Wesley Ward on the synthetics), fade horses with a "—" or "N/A" in the Gplus Polytrack column.
Identify two horses whose last three Polytrack Gplus figures average within 2 points of each other (e.g., Horse A average 62.5, Horse B average 63.0). If their morning line odds are both above 6/1, you have found a "correlated exacta." gplus polytrack
In any Polytrack race, sort the field by descending Gplus (last 3 starts, Poly only). Step 2: Discard any horse with a Gplus below 40 (unless the field is very weak). Step 3: Identify the top two rated horses. Check their sectional Gplus for the final 400m. Step 4: If both are trending upward (↑↑) and have odds above 4/1, play them straight or in an exacta.
