About HRN speed figures
HRN speed figures are AI-generated using HRN's proprietary machine-learning algorithms. Although they involve less human input than other speed figures, we see that as a plus as human adjustments often knock down surprisingly good performances to match expectations. HRN speed figures were launched in December 2024, and our expectation is also that the AI-generated speed figures will continuously get better over time.
The HRN speed figure scale goes from 1 to 160. Part of the reason for this higher scale is this helps us avoid assigning a speed figure of zero. For some products, in weaker races, half the field or more may get a speed figure of zero, which leads to inaccuracy and defeats the purpose of speed figures.
Because the HRN speed figures are based on machine learning, as we improve our models we can compute the numbers historically.
Using the top last-race speed figure as a benchmark, here are stats from 2021 to 2024 for HRN and other speed-figure providers:
Top HRN figure, 26.2% winners
Top Beyer figure, 28.1% winners
Top TimeformUS figure, 28.4% winners
Although all HRN speed figures are published on individual horse profile pages on a weekly basis, the daily reports are focused on the top and medium-tier tracks, which represent the majority of top speed figures.
