Age – Age of the Horse in years.

Claiming – An allowance in LBs assigned to apprentice jockeys (based on own personal race form)

DailyMRRank, DailyMR2Rank, DailyRPRRank, DailyORRank, DailyTSRank – The overall rank of the entire day’s racing. Lower the rank the higher rated the horse. Rank = 1 would be the highest rated horse for the entire day’s racing. Example use – If you wanted to find the day’s top 5 highest rated horses for RPR you would use the filter – DailyRPRRank <= 5.

Note – If horses are jointly rated it is down to chance which has the highest rank.

Day (1-7) – Day of the week. 1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday, 7 = Sunday

DSLR – Days Since Last Race (does not go down to the level of splitting out Flat and Jump racing for those horses that are known to try their hand at both). This is really the last time out. Where there is no available data zero (0) is used.

Furlongs – Race Length to the nearest Furlong. (8 Furlongs to a mile)

H_14D, H_30D, H_365D – Number of times out by the Horse in the last 14, 30 and 365 days.

J_14D, J_30D, J_365D – Number of races the jockey has ridden in the last 14, 30 and 365 days.

JT_14D, JT_30D, JT_365D – Number of races the trainer has had this jockey on his/her horses in the last 14, 30 and 365 days.

Jockey Win Ratio, Trainer Win Ratio, Jockey/Trainer Win Ratio, Jockey Place Ratio, Trainer Place Ratio, Jockey/Trainer Place Ratio – Either looking at the Last 14 days or the Last 6 runs (whatever was needed to get a minimum of 6 runs to calculate) this figure is the applicable strike rate.
Range from 0 – 1

L6 AVE POS. SCORE – RaceCardGuru (Data Provider) operate a Positional Scoring Matrix to help give a single value to the recent form. Range is from 0-5. This is the average positional score of the Last 6 races (or up
to last 6 if the horse hasn’t run that many yet).

L6 AVE POS. RANK – Highest L6 Ave Pos Score is Rank 1.

L6 SUM POS. SCORE – RaceCardGuru (Data Provider) operate a PositionalScoringMatrix to help give a single value to the recent form. Range is from 0-5. As well as taking an average we can also SUM. Arguably a fairer representation (particularly if horses have contested less than 6 races in their lifetime). NB. The positional scoring matrix has positive numbers as well as negatives.

L6 SUM POS. RANK – Highest L6 SUM Pos Score is Rank 1.

Merlin Rating – Provided in house. Statistics based. Values can range from around 90 to 250 with a base rate of 150.

Merlin Odds – Provided in house. The Real Odds based on the Merlin Rating.

Month (1-12) – Month of the Year. 1 = Jan …..12 = Dec

Number – The number the horse will run with to be identified.

Position ‘X’ Race Ago – Position ‘X’ Race Ago. Values from 0 to 9.
0 includes (Pulled) and (Unseated).

Provisional Odds – The Race Cards are compiled by Racecardguru.com the night before the race. Provisional Odds are the odds at the time of Race Card compilation.

Provisional Odds Rank – Lowest Odds Horse is Rank 1. Second Lowest Odds Horse is Rank 2.

POFF – Provisional Odds From Favourite – Provisional Odds minus Favourite Provisional Odds.

Predicted Position – Multiple variables are compared between each horse in the race. Predicted Position is number of runners – number of 1v1 wins. Any horse with a PP = 1 means on paper they are better than every other horse in the race. Not all positions will be filled which is why we use Predicted Rank (see below) to fill in any blanks. There can be duplicate positions however there can only be one PP = 1. Note that not every race will have a PP = 1.

Predicted Rank – Predicted Rank sorted where 1 = (Best). There can be joint ranks.

Racing Post Rating, Official Rating and Top Speed – Provided by Racing Post and BHA. Measured in pounds. Values can range from 0 to 170. All horses that do not yet have a rating are shown as 0.

Racing Post Rating Rank, Official Rating Rank, Top Speed Rank and Merlin Rating Rank – Highest Ranking Horse in the race is Rank 1. Second Highest Ranking Horse is Rank 2. And so on.

Racing Post Rating Gap, Official Rating Gap, Top Speed Gap and Merlin Rating Gap – The gap to the next ranked horse in the race.

Race Class – From 1 – 6. UK Races Only. 0 for Irish Races.

Race Class 1 Race Ago, Race Class 2 Races Ago, Race Class 3 Races Ago – From 1 – 6. UK Races Only. 0 for Irish Races. Race Class 1,2 or 3 Race Ago.

RaceName – Full RaceName containing any sponsor and any race types. See RaceType.

Race Runners – The number of horses expected to be declared.

Race Type – The RaceType is contained in the RaceName. It just has to be extracted using key words such as Hurdle, Handicap, Chase etc. The RaceType criteria simply searches the RaceName for key words. Best used with the LIST Operator.

Stall – Which stall (if applicable).

T_14D, T_30D, T_365D – Number of races the trainer has had horses in for the last 14, 30 and 365 days.

Tips – How many Newspaper/Media/Expert Tipsters have tipped the horse to win.

WeightLBs – After taking into account the Weight and the Claiming Allowance, the weight in lbs that the horse will
carry

Z-Test – (RPR-Z-Test, OR-Z-Test,TS-Z-Test,Merlin-Z-Test) – The Standard Deviation tells us the average distance of each horse from the average rating of all the horses in the race.

The Z-Test Score is the number of Standard Deviations the Rating (RPR,OR,TS or Merlin) is above or below the Average Rating in that race. If a horse is 1 standard deviation away from the average then the Z-Test Score would be 1. A horse with the exact average rating would have a Z-Test Score of Zero.

When calculating the Average Rating, all zero ratings are ignored and not included. Not all horses have RPR,OR or TS Ratings.

Z-Test Scores will range from around -5 to 3. If a Horse has a Z-Test Score of 3 it would mean that the rating in question is 3 standard deviations away from the average rating. This would indicate the Horse Rating is well above the Average Rating in that race and suggests a potentially weak field thus giving an advantage to that horse.

If no horses in a race are rated at all then the Z-Score will be zero for all horses.
