In the Smartform database, data for Ascot is split between two separately named courses "Ascot" and "Royal_Ascot" with no course_id to bind them, unlike trainers where multiple owner name variants get the same owner_id. I guess I could look through the data in detail to answer this question. Was there a name change a while back (e.g. when the enclosures were renamed), or is the split such that the Royal Ascot week long meeting each year is considered to be a different course name ? If so, are there any other meetings handled this way, or is this the only one ?
