Panalopy of irreducibly subjective judgments
Irish Freedom arrived at Churchill. |
“Synthesis is an art that requires reconciling irreducibly
subjective judgments.” Excerpt From Superforecasting, Philip E. Tetlock &

Got a newsletter via email in which exert handicapper Ellis
Starr discussed his approach to handicapping the 2018 Preakness Stakes. It
comes courtesy of Stats Race Lens, and points out the strong point of that tool
but it also highlights some analytical steps that worked (in this case) and
work without absolutely using the Stats Race Lens platform. The Preakness
winner (Justify) was easy to pick, no doubt, but the place horse (Bravazo) was harder to
pick, which Starr did, to make for a nice exacta.
"I approach handicapping the race as I do nearly every
other race," he writes. Then, he continues:
First, I take a look
at the contenders, particularly the likely betting favorite, and try to
determine whether that favorite checks off most or all of the boxes as a
legitimate favorite. A legitimate favorite is one that is logically the most
probable horse in the race to win.
After that, I go
looking for a horse, or horses, that may have a chance to succeed if the
favorite fails to run to expectations, or one that can run better than its odds
may suggest.
That involves looking for their highest speed numbers of
contestants, the recent speed number of the favorite, and then at the horses
recent trips and form. It could involve study of the trainer's success in
similar circumstances.
In examining the race
for those purposes, the first question in perusing past performances I ask
myself is "Is there are race from a horse's past that, if repeated, would
make him/her competitive?" And the second is "Can the horse repeat that
effort in this situation?"
Let's apply this process to Race 6, a 1 1/8 m Optional Claimer Allowance at Churchill Downs
on June 2, 2018.
Yes he is a steady West Coast Runner with West Coast Beyer
numbers, and has come to a new circuit and a new barn, but Favorite Irish Freedom
looks suspect to me. As a favorite he does not indisputably check off the boxes as a legitimate favorite in terms of speed, class, form or pace. His Beyer in the last out ( a third at an OC at this level
at Churchill to Lookin at Lee and Soneteer - 3 L off the winner at 1 1/16 m)
was the same (87) Beyer as his last in March at Santa Anita where he was 5 lengths
behind Prince Of Arabia. The Churchill outing is seen by some wags as a key race.
I will go past some of the others worth considering - Cause
Irish Freedom in fact will win, and pay some $5 for a $2-bet. But looking at
their last outs Big Dollar Bill's numbers look hot. Krew Chief drew off and had
best figure in last. (Describing carefully last outs seems to be a part of Mr.
Starr's heuristic (technique he uses to discover things for himself.)) Big
Dollar Bill seems in best shape demonstrably and has been second to some good
ones, Krew Chief drew off and had
best figure in last.
Here are the Beyer Numbers for top three for last races: 94
- Bill, 90-Krewe, 8-Irish.
Handicap forms for races can sometimes seem to surface a clear
theme or themes. Trackside wags at Churchill saw this race as a tale of two
themes, or maybe two more. They axed the questions 1-which could horse get
the distance (none had won at the distance); or 2-succeed given lack of pace
(there was no early speed to speak of); and 3-could back-class triumph over 4-recency (or form).
What happened in Cherry Wine's last? T'was a troublingly poor run in his first back for a horse that came in second in the Preakness two years ago. Hollywood Handsome if he reverted to better form, could vie. The question was could he run back to his 96 Beyer of N.O. Handicap race of April and would that beat these?
I myself took the backclass bait. Hollywood Handsome
appealed to me, and Cherry Wine seemed of possible value. This was a response to the Starr note: "Is there are race from a horse's past that, if repeated, would make him/her competitive?" And the second is "Can the horse repeat that effort in this situation?"
The selection: Hollywood Handsome over Irish Freedom, Big
Dollar Bill and Cherry Wine.
What happened in this one? I already told you, the Favorite won. It was
Irish Freedom over Big Dollar Bill. KREWE CHIEF set the pace early but eventually gave way, but held on for 3rd.
HOLLYWOOD HANDSOME along with CHERRY WINE pressed the pace early but tired as they entered the stretch - distance was not their friend, pace was not their helper, speed was not lately or today their forte and their back class stayed back.
What happened was IRISH FREEDOM shifted into the four path in the far turn, rallied down the lane while five wide and drove past in the late stages. BIG DOLLAR BILL got second. Recency won - there is a reason recent form gets weight in moving averages on Wall St, I guess. - Romeo.

Me thinks: Tho necessary, the very act of trying to theoretically
unseat what is likely to happen (the good favorite wins, puts you in an
immediate bind. Today was not a showcase for Romeo's ability to synthesize irreducibly
subjective judgments on the fundamental elements of form, speed, class or pace for the several runners that converged to take part in this event in Louisville.
