MCL Reference > Statistics on Past Records > HrAverage( ), JrAverage( ), SrAverage( )

The functions return averages of specified information in the past records of the horse, jockey, or stable respectively.

Syntax

HrAverage('nValueExpr',nRaces,'fCondition',nDefaultValue,cIncluding)

JrAverage('nValueExpr',nRaces,'fCondition',nDefaultValue,cIncluding)

SrAverage('nValueExpr',nRaces,'fCondition',nDefaultValue,cIncluding)

Argument

Description

Example

'nValueExpr'

•	Datum the average of which is to be found.

•	Data type of expression: Numeric

'HrDvdWin( )'

nRaces

•	Number of latest races, counting back from the underlying race, to be averaged. The races must be meeting the condition specified by 'fCondition'.

•	If nRaces is omitted, all races meeting 'fCondition' will be included.

•	If total number of races meeting 'fCondition' is smaller than nRaces, the function will perform calculations on only the available races. You may use the HrCount( ) function to check how many races have been counted.

'fCondition'

•	If argument 'fCondition' is passed, the races (nRaces) will only be selected from those meeting 'fCondition'. The 'fCondition' argument is composed of a For clause and a While clause.

•	A For clause causes the function to act on each record that meets the specified logical condition.

•	A While clause causes the function to stop action once the logical expression evaluates to false.

•	Both For and While clauses are optional.

'For HrFP( )=1 While

HrDate( )>Date(1999,9,1)'

nDefaultValue

Default value returned when no race satisfying the specified condition can be found. The data type of this value must be identical to that of normal return value.

cIncluding

When applying the function to past records, by default, races in the underlying meeting are not included. You may use this argument to change the scope. See the following page for details: The cIncluding Argument.

'R'

Returns

Numeric

Examples

HrAverage('HrWeight( )',3)

The above example returns the average loading of the past 3 races of the horse.

SrAverage('HrSpeed( )',4,'For HrDistance( )=1400')

The above example returns the average speed of the last 4 1400m starts of the stable.

JrAverage('HrSpeed( )',,'For HrDistance( )=1400 and HrAveRating( )>100',95)

The above example returns the average speed of all runs meeting the following conditions:

1.	1400m race

2.	Average rating of the race is greater than 100

If no race meeting the condition can be found, return 95.

SrAverage('HrFP( )',10,,'R')

The above function returns the average of the finishing position of last 10 starts including the starts in the underlying race.
