Number of Pastperformance Lines

If I understand correctly JCapper mainly uses the last past performance line for it's calculations.

I noticed that there are a few exceptions "bris 10" and probably the consensus factors being the most notable.

Are there other factors that use more than one past performance line for it's calculation?
I use SQL.

Thanks, Steve

Not so. It depends on the individual factor.

Some, like TPace, are based on data points read from the most recent running line.

However, many of the factors in the program are the result of using data points from multiple running lines.

For example...

• PClass, CPace, PMI, CMI, Opt Points, JRating, AProb

• JPR, PRating, QRating, Alchemy, JPRClass, CFA, JPRMLProb, UPRMLProb

• CompoundAP, CompoundSP, CompoundEarly, CompoundLate, CompundPaceFit, UPRZScoreProb, BettorsToteProb

• EarlyConsensus, LateConsensus, ClassConsensus, FigConsensus, FormConsensus, UPROpinionProb

Each of the above bullet points and the factor names to the right of the bullet point represents a "generation" of new factors introduced to JCapper over the years.

Each of the above factor names (as well as many others) are the result of using data points from multiple running lines as inputs and feeding them into algorithms which then generate resulting factor values as outputs.

Here's a link to the Glossary of Supported Factors found in JCapper page at JCapper.com:

Below is a cut and paste from the page at the above link:

"CompoundLate - CompoundLate is a measurement of late speed - ability from the the second point of call to the finish line. CompoundLate is a compound number - a mini power rating based on selected Late pace figures found in a horse's past performance record."
