Research on greyhound racing highlights several key factors influencing betting value and performance. Age and sex contribute to variations in body weight and heart weight, with males typically being heavier than females (Schoning et al., 1995). Race number also plays a role in weight fluctuations, as later races tend to be associated with greater weight loss, which can impact performance (Blythe & Hansen, 1986). Notably, moderate weight loss exceeding 2.4% has been linked to an increased likelihood of finishing in the top three, particularly in earlier races (Blythe & Hansen, 1986).
Advancements in predictive analytics, particularly through machine learning techniques, have yielded mixed results in forecasting race outcomes and optimizing betting strategies, with varying degrees of success across different wager types (Schumaker & Johnson, 2008). The favorite-longshot bias, where bettors disproportionately favor longshots, appears to decline with the introduction of off-track betting and is more pronounced in maiden races (Weinbach & Paul, 2008). Additionally, alternative probability models, such as Shin probabilities, have demonstrated superior predictive accuracy compared to individual market prices (Cain et al., 2002). Beyond betting considerations, physical attributes also affect racing performance, with evidence suggesting that race training influences hip extension, which may contribute to variations in speed and endurance (Nicholson et al., 2007).

Insufficient Detail?
At times it is difficult to answer the question as there are not enough relevant published journal articles to relate. It could be that the topic is niche, there’s a significant edge (and researchers prefer not to publish), there is no edge or simply no one has thought to investigate.
