Clarksdale, MS--the golden buckle on the cotton belt
Dosage is really a form of voodoo. In general it's rather unreliable as the current "owner", who is actually the 3rd or 4th person to keep the system in development, changes the classification if his original assessment doesn't work out.
BUT--there is a sort of scientific basis for it, since a specific gene complex has been discovered that controls a horse's predilection for sprinting and precocity or distance and slow maturing. And that's what dosage is supposed to predict. Its primary value in sport horses might be in predicting the sort of conformation that a given horse will produce, since each of the distances is generally dominated by certain body types. Other than eventing, which needs stamina for XC, there is some also some indication that jumpers benefit from more short twitch muscles, and thus can benefit from sprinting genes.
But given what we know and Dr. Roman's tendency to massage his figures after they become questionable, I'd say the current dosage system is pretty unreliable, although it can be used as one tool among many.
