It\'s been looked at elsewhere.Not really possible since the new first time gelding reporting is not always the date the horse was gelded,it\'s the date reported.Checked a few first time geldings reported in NY and the horses were gelded a couple of starts back.Useless Jockey Club should spend some of their warchest on something like accurate reporting...dont hold your breath.
13% reported first time gelding won in NY from 56 samples,ROI unknown,tops etc unknown.
