I Was asked this Derby week how to handicap by an old high school friend. (Yep, a few us are still alive.) While it would take weeks to properly teach handicapping, I’ll make some simple comments.
First, I won the Oaks, which was followed by a 2nd place nose loss by Sierra Leone in the Derby. That’s Okay. Why?
You see, Sierra Leone was the best horse in the race but didn’t win because the race paths were vastly different. While the long shot winner saved ground near the rails on both turns, Sierra ran wider in both turns, even going 5 wide coming home.
In other words, his race was near 6 lengths longer (physical impact related to the circumference of the turns half circles) for Sierra than Dan, plus a stretch battle and bumping (which is part of racing by the way) slowed him and the Japanese horse considerably.
Variation is always a funny thing and very difficult to predict. If you ever doubled down on 11 in blackjack, and on the subsequently dealt card got an Ace through 5, you might understand how you can do the right thing and lose. It’s no different in horse racing.
I once instructed executives and students related to variation, and how data science allows you to deploy statistical methods to determine true trends and probabilities. A case study could be made related to the Derby, and those that bet on the big favorite Fierceness.
The running variation related to Fierceness was extreme. His last race speed rating was great and he won by 13 1/2 lengths, but the Equibase SR was 20 points higher than the prior race, and last year as a 2 year old he had a massive 37 point swing from race to race! His variable performance indicated no predictive trend based on my analysis but the bettors, and the world at large, “always” use recent data points to predict the future, or a trend.
Just “critically” listen to the last data point false trends reported in the news any night of the week if you don’t believe me.
Speed ratings are just one algorithm element that can be used to handicap horse racing. However, do you know which two horses, in the 20 horse Derby field, had the best such average rating for “all” their races in 2024? Yep. Mystic Dan (18 to 1 really?) first, Sierra Leone second, and for all I know Forever Young could have been there also but such comparative ratings are not available in Japan.
Such is life, as an old man ponders an other example related to the importance of understanding variation.
