I haven't paid attention to dosage for quite a while, but as I understand the dosage formula, it is calculated based on the chefs-de-race in a horse's pedigree. I think Alydar had not yet qualified as a chef-de-race (not enough offspring had run?) when Strike the Gold ran. When Alydar was figured in, Strike the Gold's dosage dropped. I'm guessing the Uncle Mo's are in a similar boat. So far, the offspring of Uncle Mo (e.g., Nyquist, Outwork, Laoban, Uncle Lino) have not seemed to underperform as distances have gotten longer.
