The news is counting both morning and afternoon deaths. And to compare apples to apples, you need to be counting the same things. If the news is counting all deaths, both training and racing, then you need to count training heads and racing heads and compare that everywhere.
The number of races and number of racing days does not matter as much since the field sizes vary. There are so many factors that influence track safety including number of horses training daily, weather, number of horses racing, etc that it probably takes someone better at math and statistics than me to break this stuff down. But the news is simply counting dead horses and making a big deal over it, so trying to do damage control by saying, “But the weather” or “But the total number of races” isn’t working. I mean, no one has said that way more horses died from the neglect of one person than died all year in CA. Things need to be put in perspective.
“The owner of a Maryland farm is going to trial after dozens of horses were found dead and decaying as more than 100 others were neglected and starving on her property.”
