ROD vs ROI
Two WiseGuy reads: pace strength from ROD and support strength from ROI.
ROD
ROD, Rate of Deceleration, is the pace-performance read. It highlights horses whose run style and energy pattern fit today's race shape.
ROI
ROI, Return on Investment, is the support-signal read. It blends connections, workouts, market signal, Beyer context, and ROD agreement into one comparison.
Why Use Both
ROD and ROI are stronger together because they answer different questions. One points to race shape; the other checks whether the rest of the card supports the horse.
