Understanding the Aptitude Profile Bubble Chart

The Aptitude Profile bubble chart is generated when you select a sire and dam for analysis on the Search Page. This unique feature provides a detailed visual representation of your hypothetical mating’s distance profile, helping you assess its potential for speed or stamina.

What Does the Aptitude Profile Show?


The Aptitude Profile bubble chart highlights the ages and distances at which stakes winners, closely related to the hypothetical mating within five generations, have excelled. Stallion Match’s chart truly stands out by including every ancestor—male and female—up to five generations. Many other mating programs only evaluate the male population, but our analysis is more profound and provides a more comprehensive understanding.

  • Bubble Size: The larger the bubble, the more success the pedigree has had at that specific age and distance.
  • Distance and Age: The x-axis represents the race distances (e.g., 1200m, 1600m, 2000m), while the y-axis shows the age categories (2YO, 3YO, Open).

How to Use the Aptitude Profile


This chart is an invaluable tool for breeders aiming to evaluate their hypothetical mating’s potential:

  • Identify Strengths: Look for large bubbles to see where the pedigree has a strong history of stakes success.
  • Assess Speed or Stamina: Determine if the hypothetical pedigree leans towards producing sprinters (success at shorter distances) or stayers (success at longer distances).
  • Make Informed Decisions: This data will tailor your breeding goals, aligning them with the pedigree’s strengths.
  • Identify Each Stakes Winner: Hover over each bubble to see every stakes winner that is included within that range.

For a quick reference, hover over the tooltip on the page to see this description:

“The Aptitude Profile Chart visually represents the distances at which stakes winners, with pedigrees similar to the hypothetical mating, have performed best. Larger bubbles indicate a higher number of stakes winners excelling at that distance and age combination. Use this chart to assess the speed or stamina potential of the mating.”


Why It Matters


The Aptitude Profile doesn’t just focus on the part of the pedigree—it evaluates every ancestor up to five generations. This comprehensive analysis clarifies your hypothetical mating’s potential, empowering you to make data-driven decisions that optimise your breeding outcomes.
