All sorted now - 16:25 Newbury.

Hey TPD-Zone,
As you know, the actual race winner is often recorded as being behind the leader at the finish. Can you share any plans to enhance the accuracy of the data, particularly in terms of tracking the true position at the finish line? Really keen to know about any fixes or updates you guys are working on.

Gmax will always embrace improvements in the underlying technology and TPD themselves have taken a number of steps to improve the service - the introduction of two GPS transponders per horse, upgraded radio stations at a number of UK tracks etc.
Our data highlights that 85% of the 1.5 million horses tracked worldwide have been reported to an accuracy of within 1 meter and this statistic transposes to the UK.
It is worth bearing in mind that the GPS tracking is rarely going to be 100% accurate and we know that there is an average positional error of a head. However, two errors of that magnitude in opposite directions means an error of half a length. The error is random, each positional update being independent of the last.
Hope this provides some context.
To minimize the error , is there a specific set up that's favorable to certain races ?TPD-Zone wrote: ↑Mon Apr 29, 2024 10:29 amTo provide a summary of our GPS tracking solution; the technology was designed, developed and continues to be administered by Gmax Technologies Ltd, who work with technology and engineers from the world famous Cambridge tech cluster.lotora wrote: ↑Fri Apr 26, 2024 2:32 pm@TPD-Zone

what do you recommend as an ideal usage ...
should we avoid picking a winner in a highly competitive race , especially in the final stages of a race but rather try and pick a lay .
or go for long distance hurdles .
much appriciated

The TPD guys who are close to this have had success using a combination of the three efficiency metrics, Cadence Error, Velocity Error and Velocity Frequency - with greater weighting to each of the three metrics depending upon the race being on the flat or over obstacles.

Long distance hurdles seem to work well with Velocity Fluctuation graph providing a quick historical over view.TPD-Zone wrote: ↑Thu May 02, 2024 4:09 pm

The other three efficiency metrics including the splits could be made better when viewed in the graph format.
in the short distance races i tend to use the tool as a measurement of performance v/s the wisdom of the crowd.
and you can sometimes see races where the crowd is emotionally attached to selection and will not dump their positions irrespective of poor TPD performance.
Much appreciated
Thanks
Hi TPD ,
Firstly, can I say it is an amazing product you now have and that the possibilities are endless (and mind boggling) , well done on it.
Just two small items which I wanted to highlight that I have noticed which might help in future.
a) The vast majority of races work perfectly well but, on occasion, I have watched races where one horse number suddenly whizzes off to the side and then returns to the main body of horses. This sometimes happens repeatedly within one race and may just be one of those things. Unless I have backed Pegasus, I don't think it reflects his position! If you want I will track the next time it happens and report back the example as I don't have one to hand right now.
b) Would it be possible to tweak the software to focus the map on the main body of horses at all times. I sometimes see a horse leave the parade ring long after the others and maybe have a 40 second trip to the starting post and I notice that TPD map leaves the main group and travels back to him when I am trying to keep an eye on a larger group down at start or make note of colours etc... Not a biggie but it should be a simple enough fix as there must be some setting which caused it to track the 'late' horse in this instance?
Thanks a mill and keep up the good work,
Dave

Many thanks for the kind words. If you drop an email to [email protected] re any erroneous races, a support ticket will be raised and the guys will drill down into the race and report back. The map is supplied by a third party and used on various platforms so may be a tricky one to circumvent - you can zoom in and out which may be of some help.Morrid4 wrote: ↑Fri May 10, 2024 8:47 amHi TPD ,

I'll drop a mail next time I see a) showing up very obviously.
