The 'Horse' column displays the horse's age followed by it's offical rating, if it's having it's first run for the trainer '(FTR)' will be displayed next to it as well. The Trainer section shows the the win strike rate of the trainer for the last 14 days, 30 days, Year and then Track, you can hover over the 'Trainer' title for a reminder of the sections, as you can with all the column headings. The 'Jockey' section shows the win strike rate for the jockey with today's trainer, Year and then Track.
By clicking on the + symbol under the horse name you can expand the 'Form' section for each horse, if any of the conditions of the horses previous races match todays conditions, i.e horse ran at the same track, distance, going or field size, this will be highlighted and colour coded to show how well it ran. The distance and field size columns will be highlighted if they fall within a close range to todays value. i.e todays distance is 2m2f and the horses previous race was 2m1.5f. The other columns are SP, BSP (Betfair SP), Distance Beaten, speed rating and official rating.
This section shows details of the horse's stall draw (DR), weight carried relative to the top weighted horse and taking into account jockey's claim (WGT), days since last run (DSLR) and pace rating. These sections are colour coded based on potential negatives, if a horse is carrying a lot more weight relative to the other runners it will start to drift into the yellow orange colours, as does the DSLR column for horses that have not run for a long time. The stall draw will be coloured based on the historical strike rate of horses running from that stall, if the strike rate is particularly low it will be darker coloured, you can see in the example here that high draws at Thirsk at 6 furlongs have a low strike rate. The 'Pace' rating indicates whether a horse is likely to lead, be up with the pace or be held up at the back based on it's pace on last runs. The rating is based from 0 to 5, with 0 being held up and 5 being likley to lead, these are colour coded to show horses that are likely to have more pace showing as more green, however this not necessarily a positive or negative, it's just for quick identification purposes.
This section can be ignored for non-handicap races, it shows the difference between the horses offical rating today (OR) and it's OR on it's last run, it's last winning OR (LWM) and it's highest career OR (CHM). The example here shows that the horse is on a mark of 106 today, 10 points higher than it's last mark and and 10 points higher than it's last winning mark, however it has achieved this rating before in it's career so the 'career high mark (CHM)' value is 0. The higher these ratings go above 0 the darker coloured they will become, to indicate that this is a potential negative for the horses chance of winning today as they will be carrying more weight.
This section shows the percentage of wins and places a horse has had when running under the same Going, Distance, Class or Track as today's race and is an excellent tool to quickly see which horses are have performed best under today's race conditions. A 0% strike rate for any of these columns will be coloured more and more into the 'danger' colours (orange/red) depending on how many attempts the horse has had under that particular condition. In the example on the left, the 4th horse has had 8 attempts to win on the same going as today's race and is coloured deep red, while the 2nd horse has only has 4 attempts so is coloured orange.
The speed ratings are divided into 5 catagories:
MR - This is the Master rating and is calculated from all the other ratings.
TD - This calculated from ratings acheived under similar conditions to todays race.
LTO - The speed rating acheived on the horse's last run.
BEST - The best rating the horse has acheived in it's last 6 runs.
AVG - The average of the last 6 speed ratings acheived.
SF - This is the SpeedForm Master Rating and is an overall rating that is calculated using over 50 different variables, including the speed ratings. The horses are sorted by this rating by default as it is the most important, over 60% of all winners are found in the top 3.
EP - Early Price - This is the odds of the horse at the time the race cards are created.
