OK, any FF-owned horse that has gotten 4th or higher in a stakes should not be able to enter a claiming race or a starter allowance.
(I’m leaving maidens as fair game, since FF has practically NO maidens…probably because of races being filled with only FF-owned horses, so 1/6 of FF-owned horses win something by default )
(FYI, FF horses are entered whenever I run the script to enter them…usually the day before races are run, which is why FF horses can’t be claimed normally.)
