The sheet shows Debussy having changed trainers three times. As far as I can tell Gosden has been his trainer his entire career.
Yeah,you\'re right. When a Euro ships in it gets a new US id number. But if we have some foreign performances in the database,not necessarily all the horse has run, its identified by a different id. Trainer info is kept and assigned for all North American performances, but not neccesarily for non-North American performances where different organizations are responsible for maintaining respective databases and they don\'t necessarily integrate seamlessly, kind of like states maintaining uniform datatbases. It seldom happens. Anyway when no trainer is kept with the old database or the same trainer but identified using a different key (different database) our database reads it as a change. Simply disregard the trainer change stat when appropriate to do so. Best we can do in these cases.
