DP = 4-0-2-0-0 (6) = 4 brilliant, 0 intermediate, 2 classic, no solid, and 0 professional, for a total of 6 points altogether. Your horse leans heavily toward speed, with little stamina. Probably a sprinter type.
DI = 5.00 Dosage Index reflects the ratio of speed to stamina. Again, a 5.00 is off the scale tilted towards speed. Probably wouldn't be able to run well at classic distances of 1 1/4.
