Look up a PP on one of your horses and see how Equibase lists the partnership. If your name is in the partnership, it should come up in the results. At least mine did by my last name. The results only go back to 2000 though. I had a stable name before then, and can't find it either.
I'm sure the stats on the big boys are accurate but the site had me running a horse in the year 2000. Unless I did it in an altered reality state, um no, it didn't happen.
It had me riding a couple races at a track I never set foot on. I'm missing a few wins also. The big boys are probably off by a few too. They can only compile the info given to them. I am not sure if DRF still keeps track of it all or not. Or if Equibase gathers there own data now.
