Greyhound Speed Ratings: How to Use Sectional Times for Better Tips

Speed ratings are one of the most powerful tools available for greyhound tips. By converting raw race times into standardised ratings that account for track conditions and distance, speed ratings allow you to compare performances across different tracks, distances, and conditions. This guide explains how to calculate and use speed ratings for greyhound tips.

What Are Greyhound Speed Ratings?

A greyhound speed rating is a numerical score that represents how fast a dog ran in a particular race, adjusted for track conditions and distance. The most common approach is to calculate the difference between a dog's race time and the track record at that distance, expressed in hundredths of a second. A dog that ran 0.5 seconds slower than the track record receives a speed rating of -50 (using hundredths of a second), while a dog that equalled the track record receives a rating of 0.

For greyhound tips, speed ratings are most useful when comparing dogs that have raced at different tracks or under different conditions. A dog that recorded a speed rating of -30 at Sandown on a fast track is directly comparable to a dog that recorded -30 at Wentworth Park on a good track, even though the raw times are different.

First-Split Sectional Times: The Key to Early Pace Analysis

First-split sectional times — the time from the boxes to the first sectional marker — are the most valuable piece of speed data for greyhound tips. These times measure a dog's early pace, which is the single most important factor in determining race outcomes at short to middle distances.

For greyhound tips, calculate the average first-split time for each runner over their last five starts at the relevant track and distance. The dog with the fastest average first-split time is the early-pace leader and has a significant advantage, particularly from an inside box. When the early-pace leader also has a favourable box draw and strong track form, it is one of the most reliable greyhound tips you can make.

Adjusting Speed Ratings for Track Conditions

Track conditions have a significant impact on race times and must be accounted for when using speed ratings for greyhound tips. A 'fast' track typically produces times 0.3–0.5 seconds faster than a 'good' track, and a 'slow' track can be 0.5–1.0 seconds slower than a 'fast' track. When comparing speed ratings across different track conditions, apply an adjustment factor to normalise the times.

The state racing bodies publish track condition ratings for each meeting, and historical time data by track condition is available on most form guide websites. Using this data to adjust your speed ratings will significantly improve the accuracy of your greyhound tips.

Building a Speed Rating Database for Greyhound Tips

The most sophisticated approach to using speed ratings for greyhound tips is to build a personal database of ratings for each dog you follow. Record the speed rating for every start, along with the track, distance, box number, and track condition. Over time, this database will reveal patterns — dogs that consistently improve their speed ratings, dogs that perform better on fast tracks, and dogs that are most effective at specific distances.

This level of analysis is time-consuming but produces the most accurate greyhound tips. Even a simplified version — recording the top three speed ratings for each dog over their last ten starts — will give you a significant edge over punters who rely solely on finishing positions.
