The Track-IQ model for Churchill Downs saw excellent results on Sunday, producing eight winners from its P/S/T/Q contender structure, including five Primary selections. The model also contained four winning exactas within its top four ranked horses, highlighted by Primary–Secondary exactas in Races 1 and 9 and a Primary–Tertiary exacta in Race 7. The results continue to demonstrate the strength of the P/S/T/Q architecture, which is designed not only to identify winners but also to capture profitable exacta and trifecta combinations throughout the card. Below are the full Track-IQ PDF, Equibase results, and model performance table.
