Let me break down the possible intended terms:
Given the context, if you are looking for academic papers, reports, or retrospective analyses related to horse racing performance indices in the Americas (possibly with a focus on betting, statistical models, or historical race outcomes), I can provide a structured outline and reference sources.
However, I cannot locate a real paper titled exactly as you wrote because it does not exist in scientific or sports literature.
Los retrospectos de carreras son análisis o resúmenes detallados de carreras anteriores. Estos análisis pueden incluir estadísticas, resultados, y evaluaciones de rendimiento de los caballos, jinetes, entrenadores, y otros participantes en las carreras. retrospectos carreras %C3%ADndices americanas macaco hipico
Use the comments section (via Equibase charts or Trakus data). Did the horse wide on both turns? Was he last early and flying late?
Example: Macaco’s 4th-place finish at Saratoga (Beyer 84) included a 5-wide move into a :22.1 second quarter—suicidal pace. Adjusted, his “true” figure was ~91.

Focus: Applying American speed/class figures to past performances of a horse or entity called "Macaco Hípico" Let me break down the possible intended terms:
Retrospectively analyzing racing indices, especially in the Americas’ diverse ecological and regulatory environments, yields three key insights:
Indices are culturally and environmentally bound. A speed figure from Santa Anita (California) poorly translates to the Hipódromo de las Américas (Mexico City) without adjustments for altitude, track composition, and local bias in race calling.
The outlier, not the average, teaches most. Macaco Hípico—whether equine or algorithmic—demonstrates that low indices do not imply low probability of winning, especially when the horse’s behavioral or tactical traits (e.g., gate speed, turn agility) are omitted from the metric. "Retrospectos" → Spanish for "retrospectives" or "reviews
Retrospection reveals index manipulation. Some trainers in South America have been documented (in retrospective judicial reviews) administering mild sedatives to produce slow workout times, lowering official indices, then racing without sedatives for betting coups. A retrospective index anomaly (e.g., a horse winning 40 points above its past three figures) triggers anti-doping investigations.
His connections aimed for the Greenwood Cup (G3) at Parx. He finished 7th. The Beyer dropped to 78. Many would call him a bust. But the Ragozin revealed trouble: he clipped heels at the ¾ pole, lost 3 lengths, and was checked. Adjusted figure: 88. The retrospecto showed not decline, but bad luck.
Macaco never won a graded stakes. He retired with 6 wins from 32 starts, earnings of $189,000. On paper, pedestrian. But the indices resurrected him as a “hard-trying, unlucky, pace-dependent gelding” — a cult hero among figure bettors.
Most probable meaning:
"Retrospective of horse races using American performance indices, related to the horse ‘Macaco’ or a stable named Macaco Hípico."
