Daily Jockey Statistics
The ability of the jockey obviously has a strong effect on a horse's chances, and to assist you in assessing that ability, GTX supplies you with the Daily Jockey Stats, which arrive each day when you connect to download meetings. In the default GTX setup, these are displayed on the User-1 view, which is an additional Field View, and look like this:
Nowadays, most jockeys are declared on the day preceding a race. Many of those horses that have no jockey declared are either scratched or intended to be scratched before the morning deadline.
On the evening before a race meeting an analysis is carried out of all rides on horses that started at $8 or less in the previous 24 months for every jockey riding on the following day. The logic of using an arbitrary price of $8 allows a better comparison of 'theoretical jockey skills' (to distinguish from the top jockeys usually gaining the best rides and thereby leading the jockey table each year). It is important to note that only rides in Australia are counted.
The statistics tables present facts only; there is no personal opinion involved in the calculations and they of course can change for one jockey within a few months.
The WPR rated selection at $3 was ridden by a jockey with a relatively poor record on horses in the group.
The WPR second rated selection at $4 was ridden by a jockey with superior statistics, both in last 2 years and last 100 rides.
The second rated horse won.
The top rated horse ran 5th beaten 2.8 lengths.
In this instance this one piece of data clearly pointed to an advantage to the second rated horse over the top rated horse.
The table below which was prepared some time back allows you to line up a given jockey's S/R or POT in terms of where it historically lines up against opposition jockeys.
So, from the table above, it can be seen that if a jockey has a 20% S/R in the Daily stats then he / she is performing somewhere between the Mid-Point and Top 25% of all jockeys (based on last 2 years history of jockeys with 100+ rides up to $8 SP)
Note that the table doesn't mean a jockey with a 21.5% SR should have a 4% POT. The two measures are independent in many respects. A jockey could rank high on strike rate, but lower on POT% or vice versa.
