In many cases, there is nothing strange about many Festival statistics, but for some reason this made me double-check. With further thought, however, it makes perfect sense.
FACT: Since 2003 there have been 219 G1 races at the Festival. 68 of those races, almost a third, have been contested by horses who have raced in the last 15 days. None of them won and there were only 7 horses placed.
RULE: Do not back any horse in a Grade 1 Festival race that has raced within the last 15 days.
