# The Differentials

## The Relevant Columns

For those wishing to use the CSV to find the Differentials, a quick reference to the relevant columns is given here.

It is best to consider this section as a group of blocks; each block being concerned with one Differential.

Each of these blocks have four elements and they always come in the following order.

Historical Runs,
Historical Total,
Historical Average,
Today's Differential

The last of these four figures is usually the one that we're only interested in but the first two tells us how the Average, the third figure, was derived. The Differential figure is simply today's Class (or Weight) with the Average subtracted from it.

Each block of Differentials can be viewed as follows

The 5 Year Differentials
 Start Column End Column Differential EL EO Class Differential EP ES Win Class Differential ET EW Weight Differential EX FA Win Weight Differential FB FE Sum of Class + Weight Differentials FF FI Sum of Win Class + Weight Differentials
The 1 Year Differentials
 Start Column End Column Differential FV FY Class Differential FZ GC Win Class Differential GD GG Weight Differential GH GK Win Weight Differential GL GO Sum of Class + Weight Differentials GP GS Sum of Win Class + Weight Differentials

A fuller description of the above three tables is expanded here below.

Full Description
 Column Title Explanation EL/FV Class Diff. Runs Number of races run in same race type to work out the Class Differential average EM/FW Class Diff. Total Sum of all Class ratings for races entered of same type EN/FX Class Diff. Average Average of the above EO/FY Class Diff. Difference Difference between today's race class and average race class ran EP/FZ Class Diff. Wins Runs The same as the Class Differential but only considering races won EQ/GA Class Diff. Wins Total ER/GB Class Diff. Wins Average ES/GC Class Diff. Wins Difference The class difference between today's race and the races this horse has won. ET/GD Weight Diff. Runs Number of races run in same race type to work out the Weight Differential average EU/GE Weight Diff. Total Sum of all Weights carried for races entered of same type EV/GF Weight Diff. Average Average of the above EW/GG Weight Diff. Difference Difference between today's weight and average weight carried EX/GH Weight Diff. Wins Runs The same as the Weight Differential but only considering races won EY/GI Weight Diff. Wins Total EZ/GJ Weight Diff. Wins Average FA/GK Weight Diff. Wins Difference The Weight difference between today's race and the weight in the races won.
 FB/GL Class+Weight Diff. Runs As the previous eight columns, but looking at the Class & Weight combined. FC/GM Class+Weight Diff. Total FD/GN Class+Weight Diff. Average FE/GO Class+Weight Diff. Difference FF/GP Class+Weight Diff. Wins Runs FG/GQ Class+Weight Diff. Wins Total FH/GR Class+Weight Diff. Wins Average FI/GS Class+Weight Diff. Wins Difference

The CSV has since been expanded since the above was written to include rankings of the various differentials within a race.

These fields are as follows.
