Please note that several of the terminologies and symbols below will not be evident unless you have subscribed to the additional options they relate to.

ADE
Acceleration/Deceleration Effect based on measured advantage or disadvantage relating to the change in distance and weight to be carried when today's details are compared to qualifying run or last start.

All
Jockey Allowance
An allowance that reduces the weight the horse carries, which apprentice jockeys may claim to offset their relative lack of experience. The allowance can range from 1.5kg to 4.0kg and is relative to the apprentice's winning record. For example, apprentices can claim 4kg if they have ridden less that 5 winners. The allowance cannot be claimed in some races, and in these cases the race details on the GTX Race Details bar includes the tag NA.

API
Average Prizemoney Index, which is derived from career earnings, divided by number of career starts, divided by 1000. The API gives an indication of the horse's average earnings per start.

BP
BPen
Barrier Penalty
The Barrier Penalty is an arbitrary figure, expressed in kilos, which indicates the degree to which a horse is theoretically disadvantaged by having to start from a wider barrier.

Base
The Base Rating is derived from the Rating assigned to the Qualifying Run chosen by GTX. The bonuses and penalties are adjusted to and from this rating.

Bog Factor
Bonus or penalty expressed in kilograms or points given to each horse according to its career statistics on combined Slow and Heavy track runs (range: -9.0kg to +6.0kg)

Break
42 to 55 days break from racing.

CV
CVal
Class Value
Race Class Value, is an open ended field strength expressed in kilograms; a numeric assessment used by weight rating techniques to separate fields of different strength. It is important to realise that races of the same 'Class' are often quite different in terms of field strength. For example, a Welter handicap at Randwick on a Saturday will naturally be stronger than a Welter handicap at Goulburn on a Friday even though they are both Welter handicaps. The Class Value of the race at Randwick will be some 10Kg stronger (higher) than the Goulburn race. The general range is -32 (weakest class) to +12 (strongest class).

Races in which there are fewer than five horses with prior runs will not display a Class Value, simply because there is insufficent data available to calculate a reliable value for that race.

Class Value is a component of the Formline ratings.

Cval Change
CValCh
Class Value Change, as compared to last start, derived from the change in the strength of the field. The Class Values range is an open-ended scale generally ranging from -30.0kg to +12.0kg.

Class value is component of the Formline ratings.

Cond
Going
Condition or state of the track, ie. Heavy, Slow, Dead, Good or Fast.

Cons
Consistency
A bonus that is more or less a rating in its own right. This bonus is derived from the proximity to the winner from each horse's last 10 starts weighted by race prizemoney.

Course
Within GTX, a Course is a Track/Distance combination, whereas a Track is the location, or venue, of a race meeting.

Randwick is a Track.
Randwick 1200m is a Course
Randwick 1400m is a different Course

The distribution is the 'exponent' in a formula that determines the distribution of the odds between all runners in a race. The exponent must be negative so that the highest rated horse is the shortest price.

An example, using extreme settings and approximate prices...

With the default setting of -0.20, the market spread may be say $2.00 for the top rated horse and $500 for the hopeless outsider.

In the same race a change of distribution to –0.01 created a market spread between $8.00 for the top rated horse and $11.00  for the outsider.

A distribution of –0.99 created a market spread between $1.00 for the top rated horse to $999 for a number of lower rated runners

Dual Acceptors
Horses which have accepted for more than one race amongst the meetings that have been loaded, even though those meetings may be on more than one day. This could include horses that have accepted for two races at one meeting, or one race at each of two or more meetings.

Dummy
Dummy signifies that the jockey's name was not available when the jockey file was created.

FinPos
FP
Finishing Position

First Starter
A horse having its first ever race start

Firstup
A horse's first race start on returning from a Spell- as distinct from a First Starter, which is a horse having its first ever race start.

Generic
Related to the currently selected rating/ranking order. If you had the Generic Price column selected for display in the Field View, the values would represent the rated odds of the currently selected rating/ranking order. For example if you had the Field View ranked in GTX order, the values in the Generic Price column would be the GTX rated odds - if you ranked the field in Trakform order, the Generic Price column would show the Trakform rated odds.

In contrast to that, if you had say the GTX Price column in the Field View, that column would always display the GTX rated odds, even if you had the field ranked by Trakform or Formline or any other ranking. Same with the other ratings: Trakform Price will always display Trakform rated odds; Formline Price will always display Formline rated odds.

Going
State or condition of the track, ie. Heavy, Slow, Dead, Good or Fast

Hf
Horse's in running position at the half mile (800m)

In-runs
Horse's position in running

Jockey Allowance
All
An allowance that reduces the weight the horse carries, which apprentice jockeys may claim to offset their relative lack of experience. The allowance can range from 1.5kg to 4.0kg and is relative to the apprentice's winning record. For example, apprentices can claim 4kg if they have ridden less that 5 winners. The allowance cannot be claimed in some races, and in these cases the race details on the GTX Race Details bar includes the tag NA.

Jockey Penalty
JPen
JP
Jockey Penalty is effectively a rating given to jockeys that reflects a combination of their medium and long-term normalised winning strike rate on genuine winning chances. As such the formula considers only horses under 10/1 that finished within 10 lengths of the winner and the penalty is weighted by proximity to the winner in lengths. Only the last 100 rides are considered.

The Jockey Penalties range from 0.0 to 5.0 where zero represents the best rating/penalty. 'Normalised' means that adjustments are made to the figures to allow for the fact that there is a difference in the level of jockey quality/competition in Metropolitan areas compared to non Metrpolitan areas. For example, a jockey with a 23% strike rate who has had 90% of his/her rides at Metro venues cannot be assessed in the same way as a jockey with a 23% strike rate who has had 90% of his/her rides at Country tracks. The Jockey Penalty takes this into account.

Once normalised, strike rates are ranked and Jockey Penalty values are allocated on a percentile basis. The bottom 33% of riders receive a Jockey Penalty of 5.0 and the remaining values are allocated in even groups based on jockey rank.

Unknown jockeys (Dummy) are rated at 5.5

The Jockey Penalties are recalculated approximately every month so that they remain current.

Letup
28 to 41 days break from racing.

Limit Weight
The lowest weight, specified by rules, that a race club handicapper can allot to any horse in a given race. A horse can carry less than this weight when an apprentice's allowance is claimed. Not applicable in set weight or WFA races.

Margin
Marg
The distance, measured in lengths, between a particular horse and the winner of the race at the finish. The winning margin is the distance between the first and second horse. In the case of the winner the distance between it and the second horse is expressed as a negative value (e.g. -2.5 lengths)

Min Form Size
This is a parameter on the Race tab in the System Developer with which you can specify the number of starts that all runners in a race must have for the race to qualify. For example, if you don't want to bet in a race unless all horses have had at least four starts, you should set Min Form Size to Min 4   Max 99

ML
MLine
Morning Line Odds
An estimate of what a horse’s opening price will be, based on its prior performance and in relationship to the other horses in the race. Morning Line odds differ from ratings in that the market percentage for each race can vary dependent on field sizes and whether the meeting is a Metropolitan or Country meeting.

Mud Factor
Bonus or penalty expressed in kilograms or points given to each horse according to its career statistics on combined Dead and Slow track runs (range: -9.0kg to +6.0kg)

Nett
Final rating derived by adding and subtracting bonuses and penalties to and from the Base rating.

Other
Oth
Depending on the rating it is applicable to, this bonus or penalty is the nett of one or more adjustments and is designed to improve the performance of that rating.

Overlay
An overlay represents the degree of difference between a selected rating and another rating that you have specified under overlay reference in Setup>Ratings (Extended). It’s a comparison between two ratings.

Let’s say you had selected the GTX rated odds and were referencing them against the Morning Line odds. If the GTX odds were 2.0 and the Morning Line (ML) odds were 4.0, then an overlay situation exists. If the figures were reversed, it would be regarded as an underlay.

Qualifying Run
QR
The Rating Qualifying Run is the historical run selected by each rating process as the most suitable run on which to base today's rating. Its rating value represents the base rating for today's assessment. Each rating uses different logic to select the QR. No QR exists for the GTX Rating.

Secondup
A horse's second race start after returning from a Spell

Spell
56 days or more break from racing.

(SWP)
Starts - Wins - Placings
30 - 3 - 4 means 30 starts for 3 wins and 4 placings (not including wins)

SD
Horse's in running position when field settled down

TCDWHB

These are information flags that can be included in Form printouts in the Horse section.

Their meanings are:

Tn
Horse's in running position at the home turn

Track
Within GTX, a Track is the location of a race meeting, whereas a Course is a Track/Distance combination.

Randwick is a Track.
Randwick 1200m is a Course
Randwick 1400m is a different Course

And Randwick Inner is a different track.

Venue
The normal location at which a stable return indicates that a horse is trained

WFA
Weight for Age. A standard scale of weights that allocates weight according to a horse's age and sex, rather than its previous performances.

*
**
***
One, two or three asterisks (also referred to as 'stars') are occasionally assigned against a post race rating as an indicator of expected improvement. Each * indicates 1.5kg expected improvement and is factored in to the weight rating when the run it relates to is chosen as the Qualifying Run. Relates only to the Formline Ratings.

+
A Plus sign against an historical weight rating generally indicates that the horse may as well have stayed in its stable on that day. It is assigned by our handicapper and factored in to the 'other' bonus as a 6kg improvement if the rating from that run is used as the Qualifying Run. Relates only to the Formline Ratings.

c
Some Ratings have a ‘c’ flag next to them. The ‘c’ flag indicates that the rating assigned to that run was generated by the computer because it relates to overseas form or a rating which has been produced in advance of final results being processed for that historical race. Relates only to the Formline Ratings.
